Update Tender Approval Status to Include Submitted State and Revise API Documentation

- Changed the approval status from "approved" to "submitted" in various locations, including entity definitions, forms, and service methods, to accurately reflect the tender approval process.
- Updated API documentation in Swagger JSON, YAML, and Go files to describe the new status options ("submitted" and "rejected") and their corresponding descriptions.
- Enhanced the tender approval statistics structures to include a count for submitted tenders, improving the overall data model for tender management.
- These changes ensure clarity in the tender approval workflow and enhance the usability of the API for clients interacting with tender approvals.
