Add endpoints and functionality for verifying duplicates in Lora and Checkpoints

- Implemented `/api/loras/verify-duplicates` and `/api/checkpoints/verify-duplicates` endpoints.
- Added `handle_verify_duplicates` method in `ModelRouteUtils` to process duplicate verification requests.
- Enhanced `ModelDuplicatesManager` to manage verification state and display results.
- Updated CSS for verification badges and hash mismatch indicators. Fixes #221
