- Added new routes for both admin and public access to tender submissions, allowing for listing, ensuring, and retrieving submissions by ID and tender.
- Enhanced the tender approval service to synchronize submission workflows with approval changes, ensuring proper state management.
- Implemented validation and response structures for tender submission operations, improving API consistency and usability.
- Added unit tests for tender submission status transitions and workflow logic, ensuring robust functionality.
