Add configuration file and update server settings

- Introduced a new `config.yaml` file for managing server, database, cache, queue, AI, scraping, logging, and rate limiting configurations. - Updated `docker-compose.yml` to reflect the new server port (8081) and adjusted health check endpoints accordingly. - Modified `Dockerfile` to expose the new server port. - Updated `README.md` to reflect changes in server configuration and added documentation for the new configuration structure. - Added test scripts for server and Swagger documentation testing. - Refactored customer domain structure to align with new configuration settings and improve maintainability.

-# Tender Management System - Dual User Architecture
+# Tender Management System

-A comprehensive tender management backend system built with Go, featuring separate authentication and authorization for mobile app customers and panel admin users.
+A comprehensive tender management backend system built with Go, following Clean Architecture principles with Domain-Driven Design (DDD) patterns.

-## 🏗️ Architecture Overview
+## 📚 Documentation

-This system implements **Clean Architecture** principles with a dual user system:
+All documentation has been organized in the [`docs/`](./docs/) directory for better structure and maintainability.

-### User Types
-
-1. **Customers (Mobile App Users)**
-   - End users who interact through mobile applications
-   - Can register, view tenders, manage company profiles
-   - Role-based access: `customer_user`, `customer_manager`
-
-2. **Panel Users (Admin/Staff)**  
-   - Administrative users who manage the system
-   - Can manage customers, tenders, companies, and system settings
-   - Role-based access: `admin`, `moderator`, `support`, `analyst`
-
-### Layer Structure

+# Tender Management System Documentation
+
+Welcome to the Tender Management System documentation. This directory contains all the documentation for the Go backend API following Clean Architecture principles with Domain-Driven Design (DDD) patterns.
+
+## 📚 Documentation Structure
+
+### 📖 Main Documentation
+- **[README.md](./README.md)** - Main project documentation and overview
+- **[AEC_TenderManagement.md](./AEC_TenderManagement.md)** - Comprehensive project requirements and specifications
+
+### 🔧 Setup & Configuration
+- **[setup/HTTP_SERVER_SETUP.md](./setup/HTTP_SERVER_SETUP.md)** - HTTP server configuration and setup guide
+- **[setup/SWAGGER_SETUP.md](./setup/SWAGGER_SETUP.md)** - Swagger/OpenAPI documentation setup
+- **[setup/SWAGGER_SUCCESS.md](./setup/SWAGGER_SUCCESS.md)** - Swagger implementation success guide
+
+### 🚀 Implementation
+- **[implementation/IMPLEMENTATION_SUMMARY.md](./implementation/IMPLEMENTATION_SUMMARY.md)** - Implementation details and architecture overview
+
+### 📡 API Documentation
+- **[examples/API_EXAMPLES.md](./examples/API_EXAMPLES.md)** - API usage examples and endpoints documentation
+
+## 🏗️ Project Architecture
+
+### Clean Architecture Layers
+- **Domain Layer** (`internal/{domain}/`): Business entities, aggregates, interfaces, and core business rules
+- **Service Layer** (`internal/{domain}/service.go`): Business logic and use cases
+- **Handler Layer** (`internal/{domain}/handler.go`): HTTP controllers and request/response handling
+- **Repository Layer** (`internal/{domain}/repository.go`): Data access implementations
+- **Infrastructure Layer** (`infra/`): External dependencies (DB, cache, queues, config)
+
+### Domain Structure Pattern
+Each domain follows this flat structure:
+```
+internal/{domain}/
+├── entity.go                  # Core domain entities
+├── aggregate.go               # Aggregate roots and DTOs
+├── repository.go              # Repository interface and implementation
+├── service.go                 # Business logic and use cases
+├── form.go                    # Request/response forms with validation
+└── handler.go                 # HTTP controllers and request/response handling
+```
+
+## 🚀 Quick Start
+
+1. **Setup Environment**
+   - Follow the setup guides in the `setup/` directory
+   - Configure MongoDB and other dependencies
+
+2. **Run the Application**
+   ```bash
+   make run
+   ```
+
+3. **Access API Documentation**
+   - Swagger UI: `http://localhost:8081/swagger/index.html`
+   - API Base URL: `http://localhost:8081/api/v1`
+
+## 📋 Key Features
+
+- **Clean Architecture**: Follows DDD principles with clear separation of concerns
+- **MongoDB Integration**: Robust data persistence with proper indexing
+- **Structured Logging**: Comprehensive logging with context
+- **Input Validation**: Govalidator integration for request validation
+- **Error Handling**: Consistent error responses and logging
+- **Time Handling**: Unix timestamps throughout the application
+- **API Documentation**: Auto-generated Swagger documentation
+
+## 🔧 Development Guidelines
+
+### Code Organization
+- All domain files use the same package name for easy access
+- Repository interfaces and implementations are in the same file
+- Use dependency injection through constructors
+- Follow Go naming conventions and best practices
+
+### Time Handling
+- **Input**: Accept Unix timestamps (int64) for all time fields
+- **Storage**: Store as Unix timestamps (int64) in MongoDB
+- **Output**: Return Unix timestamps (int64) for all time fields
+- **Consistency**: All time operations use Unix timestamps throughout
+
+### Validation
+- Use govalidator for all request validation
+- Define validation tags in request structs
+- Register custom validators for complex rules
+- Validate at handler level before calling services
+
+## 📝 Logging Standards
+
+### Structured Logging
+```go
+log.Info("Customer authenticated successfully", map[string]interface{}{
+    "customer_id": customer.ID.String(),
+    "email":       customer.Email,
+    "ip":          clientIP,
+})
+```
+
+### Log Levels
+- `Debug`: Detailed debugging information
+- `Info`: General operational messages
+- `Warn`: Warning conditions that should be addressed
+- `Error`: Error conditions that need attention
+- `Fatal`: Critical errors that cause program termination
+
+## 🗄️ Database Patterns
+
+### MongoDB Integration
+- Use BSON tags for field mapping
+- Create indexes in repository constructors
+- Handle duplicate key errors appropriately
+- Use Unix timestamps for all time fields
+- Implement proper pagination with limit/offset
+
+### Repository Pattern
+```go
+type CustomerRepository interface {
+    Create(ctx context.Context, customer *Customer) error
+    GetByID(ctx context.Context, id string) (*Customer, error)
+    Update(ctx context.Context, customer *Customer) error
+    Delete(ctx context.Context, id string) error
+    List(ctx context.Context, limit, offset int) ([]*Customer, error)
+}
+```
+
+## 🌐 HTTP Handler Guidelines
+
+### Request Handling
+- Validate all incoming requests using govalidator
+- Use proper HTTP status codes
+- Return consistent API response format
+- Handle CORS appropriately
+- Accept Unix timestamps (int64) for all time fields
+
+### Response Format
+```json
+{
+    "success": true,
+    "data": {...},
+    "message": "Operation successful",
+    "metadata": {...}
+}
+```
+
+## 🔐 Security Best Practices
+
+- Validate and sanitize all inputs
+- Use proper authentication middleware
+- Implement rate limiting
+- Never log sensitive information
+- Use HTTPS in production
+- Validate JWT tokens properly
+
+## 🧪 Testing Guidelines
+
+- Write unit tests for all business logic
+- Use table-driven tests for multiple scenarios
+- Mock external dependencies using interfaces
+- Test error cases, not just happy paths
+- Use meaningful test names
+
+## 📦 Dependencies
+
+### Core Dependencies
+- **Echo**: HTTP framework
+- **MongoDB**: Database driver
+- **Govalidator**: Request validation
+- **JWT**: Authentication
+- **Swagger**: API documentation
+
+### Development Dependencies
+- **Swag**: Swagger documentation generation
+- **Testify**: Testing utilities
+
+## 🚨 Common Issues & Solutions
+
+### Time Handling
+- **Issue**: Inconsistent time formats
+- **Solution**: Always use Unix timestamps (int64) throughout
+
+### Validation
+- **Issue**: Missing request validation
+- **Solution**: Use govalidator tags in request structs
+
+### Error Handling
+- **Issue**: Exposed internal errors
+- **Solution**: Use structured error responses

+# API Examples
+
+This document provides examples of how to interact with the Tender Management API using curl commands.
+
+## Prerequisites
+
+1. **Start MongoDB**:
+   ```bash
+   sudo systemctl start mongod
+   ```
+
+2. **Start the server**:
+   ```bash
+   make run
+   ```
+
+3. **Verify server is running**:
+   ```bash
+   curl http://localhost:8081/health
+   ```
+
+## Customer Management Examples
+
+### 1. Register a New Customer (Admin Only)
+
+```bash
+curl -X POST http://localhost:8081/api/admin/customers/register \
+  -H "Content-Type: application/json" \
+  -d '{
+    "full_name": "John Doe",
+    "username": "johndoe",
+    "email": "john@example.com",
+    "mobile": "+1234567890",

+#!/bin/bash
+
+BASE_URL="http://localhost:8081"
+
+echo "Testing Tender Management API..."
+
+# Test health endpoint
+echo "1. Testing health endpoint..."
+curl -s "$BASE_URL/health" | jq .
+
+# Register a customer
+echo "2. Registering a customer..."
+CUSTOMER_RESPONSE=$(curl -s -X POST "$BASE_URL/api/admin/customers/register" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "full_name": "Test User",
+    "username": "testuser",
+    "email": "test@example.com",
+    "mobile": "+1234567890",
+    "password": "password123"
+  }')
+
+echo "$CUSTOMER_RESPONSE" | jq .
+
+# Extract customer ID
+CUSTOMER_ID=$(echo "$CUSTOMER_RESPONSE" | jq -r '.data.id')
+
+if [ "$CUSTOMER_ID" != "null" ]; then
+    echo "Customer ID: $CUSTOMER_ID"
+    
+    # Test login
+    echo "3. Testing login..."
+    curl -s -X POST "$BASE_URL/api/customers/login" \
+      -H "Content-Type: application/json" \

+    echo "5. Testing list customers..."
+    curl -s -X GET "$BASE_URL/api/admin/customers" | jq .
+fi
+
+echo "Testing completed!"
+```
+
+## Notes
+
+1. **Authentication**: Currently using a simple header-based authentication (`X-Customer-ID`). In production, this should be replaced with proper JWT token validation.
+
+2. **Timestamps**: All timestamps are Unix timestamps (int64) for consistency.
+
+3. **Validation**: All requests are validated using govalidator with custom validation rules.
+
+4. **Error Handling**: All errors return consistent JSON responses with appropriate HTTP status codes.
+
+5. **CORS**: The server is configured to allow all origins for development. Configure properly for production.

+The API documentation is generated using [Swag](https://github.com/swaggo/swag) and served using [echo-swagger](https://github.com/swaggo/echo-swagger). The documentation provides an interactive interface to explore and test all API endpoints.
+
+## 🚀 Quick Start
+
+### 1. Generate Documentation
+
+```bash
+# Generate Swagger documentation
+make docs
+
+# Or manually
+swag init -g cmd/web/main.go -o cmd/web/docs
+```
+
+### 2. Start Server with Documentation
+
+```bash
+# Build and run with documentation
+make run-docs
+
+# Or manually
+make build
+./bin/web
+```
+
+### 3. Access Documentation
+
+Open your browser and navigate to:
+- **Swagger UI**: http://localhost:8081/swagger/index.html
+- **Health Check**: http://localhost:8081/health
+
+## 📋 Available Endpoints
+
+### 🔐 Authentication
+- `POST /api/customers/login` - Customer login
+- `POST /api/customers/refresh-token` - Refresh access token
+
+### 👤 Customer Profile (Protected)
+- `GET /api/customers/profile` - Get customer profile
+- `PUT /api/customers/profile` - Update customer profile
+- `PUT /api/customers/change-password` - Change password
+
+### 📱 Device Management (Protected)
+- `POST /api/customers/device-token` - Add device token
+- `DELETE /api/customers/device-token` - Remove device token
+
+### 👥 Admin Operations (Admin Protected)
+- `POST /api/admin/customers/register` - Register new customer
+- `GET /api/admin/customers` - List customers
+- `GET /api/admin/customers/{id}` - Get customer by ID
+- `PUT /api/admin/customers/{id}/status` - Update customer status
+
+## 🛠️ Development
+
+### Adding New Endpoints
+
+1. **Add Swagger Annotations** to your handler functions:
+
+```go
+// @Summary Endpoint summary
+// @Description Detailed description
+// @Tags tag-name
+// @Accept json
+// @Produce json
+// @Security BearerAuth
+// @Param param-name param-type param-required "param description"
+// @Success 200 {object} response.APIResponse{data=YourResponseType} "Success description"
+// @Failure 400 {object} response.APIResponse "Error description"
+// @Router /api/endpoint [method]
+func (h *Handler) YourHandler(c echo.Context) error {
+    // Your handler implementation
+}
+```
+
+2. **Regenerate Documentation**:
+
+```bash
+make docs
+```
+
+### Swagger Annotation Examples
+
+#### Basic GET Endpoint
+```go
+// @Summary Get resource
+// @Description Get a resource by ID
+// @Tags resources
+// @Accept json
+// @Produce json
+// @Param id path string true "Resource ID"
+// @Success 200 {object} response.APIResponse{data=ResourceResponse}
+// @Failure 404 {object} response.APIResponse
+// @Router /api/resources/{id} [get]
+```
+
+#### POST with Request Body
+```go
+// @Summary Create resource
+// @Description Create a new resource
+// @Tags resources
+// @Accept json
+// @Produce json
+// @Param resource body CreateResourceForm true "Resource data"
+// @Success 201 {object} response.APIResponse{data=ResourceResponse}
+// @Failure 400 {object} response.APIResponse
+// @Router /api/resources [post]
+```
+
+#### Protected Endpoint
+```go
+// @Summary Protected endpoint
+// @Description This endpoint requires authentication
+// @Tags resources
+// @Accept json
+// @Produce json
+// @Security BearerAuth
+// @Success 200 {object} response.APIResponse
+// @Failure 401 {object} response.APIResponse
+// @Router /api/protected [get]
+```

+└── ...
+
+pkg/response/
+└── response.go     # Standard API response types
+```
+
+## 🔧 Configuration
+
+### Swagger Configuration
+
+The main Swagger configuration is in `cmd/web/docs.go`:
+
+```go
+// @title Tender Management API
+// @version 1.0.0
+// @description This is the API documentation for the Tender Management System.
+// @host localhost:8081
+// @BasePath /api/v1
+// @securityDefinitions.apikey BearerAuth
+// @in header
+// @name Authorization
+```
+
+### Server Configuration
+
+The Swagger endpoint is registered in `cmd/web/bootstrap.go`:
+
+```go
+// Add Swagger documentation endpoint
+e.GET("/swagger/*", echoSwagger.WrapHandler)
+```
+
+## 🧪 Testing
+
+### Using the Test Script
+
+```bash
+# Run the test script
+./test_swagger.sh
+```
+
+This script will:
+1. Build the application
+2. Start the server
+3. Display all available endpoints
+4. Provide access URLs
+
+### Manual Testing
+
+1. **Start the server**:
+   ```bash
+   make run-docs
+   ```
+
+2. **Access Swagger UI**:
+   - Open http://localhost:8081/swagger/index.html
+   - Explore and test endpoints interactively
+
+3. **Test Health Check**:
+   ```bash
+   curl http://localhost:8081/health
+   ```
+
+## 📝 Response Types
+
+### Standard Response Structure
+
+All API responses follow this structure:
+
+```json
+{
+  "success": true,
+  "message": "Operation successful",
+  "data": {
+    // Response data
+  },
+  "meta": {
+    // Pagination metadata (if applicable)
+  },
+  "error": {
+    // Error details (if applicable)
+  }
+}
+```
+
+### Error Response
+
+```json
+{
+  "success": false,
+  "message": "Error message",
+  "error": {
+    "code": "ERROR_CODE",
+    "message": "Detailed error message",
+    "details": "Additional details"
+  }
+}
+```
+
+## 🔐 Authentication
+
+### Bearer Token Authentication
+
+Most endpoints require Bearer token authentication:
+
+1. **Login** to get access token:
+   ```bash
+   curl -X POST http://localhost:8081/api/customers/login \
+     -H "Content-Type: application/json" \
+     -d '{"email": "user@example.com", "password": "password"}'
+   ```
+
+2. **Use the token** in subsequent requests:
+   ```bash
+   curl -X GET http://localhost:8081/api/customers/profile \
+     -H "Authorization: Bearer YOUR_ACCESS_TOKEN"
+   ```
+
+## 🚨 Troubleshooting
+
+### Common Issues
+
+1. **Documentation not updating**:
+   ```bash
+   make clean
+   make docs
+   make build
+   ```
+
+2. **Swagger annotations not recognized**:
+   - Ensure annotations are directly above the function
+   - Check for syntax errors in annotations
+   - Verify import paths are correct
+
+3. **Server won't start**:
+   - Check if port 8081 is available
+   - Verify MongoDB connection
+   - Check configuration files
+
+### Debug Commands
+
+```bash
+# Check if swag is installed
+swag --version
+
+# Generate docs with verbose output
+swag init -g cmd/web/main.go -o cmd/web/docs --parseDependency
+
+# Check generated files
+ls -la cmd/web/docs/
+```

+# Customer Management Module
+
+This module implements a complete User Management system for the Tender Management System, allowing administrators to register users who can later access the mobile application.
+
+## Features
+
+### 1. User Registration (by Admin)
+- **Fields**: Full name, username, email, mobile number, password (hashed), national ID (optional), gender (enum), birthdate (optional), profile image (optional), user status (active/inactive), registration date
+- **Uniqueness**: Ensures uniqueness for email, mobile, and username
+- **Validation**: Comprehensive input validation using govalidator
+
+### 2. Authentication for Mobile Users
+- **Login**: Secure login via email or mobile number + password
+- **JWT Tokens**: Access and refresh token generation
+- **Password Security**: bcrypt hashing for secure password storage
+
+### 3. Device Token Management
+- **Storage**: Saves device_token and device_type (Android/iOS) when user logs in
+- **Updates**: Updates token if user logs in from new device or re-installs app
+- **Cleanup**: Endpoint to delete token on logout
+
+### 4. User Profile Management
+- **View/Edit**: Personal info (name, email, mobile, etc.)
+- **Password Change**: Secure password change endpoint
+- **Profile Picture**: Upload/update profile picture support
+
+### 5. Push Notification Ready
+- **Multiple Tokens**: Stores multiple device tokens per user
+- **User Association**: Tokens tied to correct user ID
+- **Admin Access**: API to get all active device tokens for admin push campaigns
+
+### 6. Admin Panel APIs
+- **List/Search/Filter**: Users by name, mobile, email, registration date, and status
+- **Status Management**: Activate/deactivate users
+- **Role Support**: Framework for role assignment (user, moderator, etc.)
+
+### 7. Security & Best Practices
+- **Input Validation**: Comprehensive validation and sanitization
+- **Rate Limiting**: Framework for authentication endpoint rate limiting
+- **Password Security**: bcrypt hashing with configurable cost
+- **HTTP Status Codes**: Proper status codes and error messages
+- **Activity Logging**: User activities (login, logout, profile update)
+
+## Architecture
+
+### Clean Architecture Implementation
+- **Domain Layer**: Business entities, aggregates, interfaces, and core business rules
+- **Service Layer**: Business logic and use cases
+- **Handler Layer**: HTTP controllers and request/response handling
+- **Repository Layer**: Data access implementations
+- **Infrastructure Layer**: External dependencies (DB, cache, queues, config)
