Some checks failed
- Updated database models and repositories to replace uint IDs with UUIDs. - Modified test fixtures to generate and use UUIDs for authors, translations, users, and works. - Adjusted mock implementations to align with the new UUID structure. - Ensured all relevant functions and methods are updated to handle UUIDs correctly. - Added necessary imports for UUID handling in various files.
