Refactor Tender Approval Management and Update API Documentation

- Replaced the existing tender approval update and delete endpoints with a new toggle functionality, allowing for more streamlined management of tender approvals.
- Introduced the `ToggleTenderApproval` method in the service layer to handle both approval and rejection actions based on the current state of the tender approval.
- Updated the API documentation to reflect the new endpoint structure and response formats, including the `TenderApprovalWithTenderResponse`.
- Enhanced Swagger documentation to ensure accurate representation of the updated tender approval operations.
- Removed obsolete methods and routes to maintain a clean and efficient codebase, adhering to Clean Architecture principles.
