feat: Integrate audit logging for various operations

- Added audit logging functionality across multiple controllers, including menu, user, department, flow, screen, and table management.
- Implemented logging for create, update, and delete actions, capturing relevant details such as company code, user information, and changes made.
- Enhanced the category tree service with a new endpoint to check if category values are in use, improving data integrity checks.
- Updated routes to include new functionalities and ensure proper logging for batch operations and individual record changes.
- This integration improves traceability and accountability for data modifications within the application.
