- 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.

Domain-Driven Design
- ✅ Domain Entities - Customer entity with business rules
- ✅ Aggregates - Customer as aggregate root
- ✅ Repositories - Data access abstraction
- ✅ Services - Business logic encapsulation
- ✅ Value Objects - DeviceToken, Gender, etc.
Go Best Practices
- ✅ Package Structure - Flat domain structure
- ✅ Error Handling - Explicit error handling
- ✅ Interface Design - Repository and service interfaces
