Update database schema and synchronization logic

- Add `useEffect` in `ScribeLeftBar` for handling book state changes.
- Extend `BooksSyncContext` with new properties and stricter typings.
- Refine `Repositories` to include `lastUpdate` handling for synchronization processes.
- Add comprehensive `fetchComplete*` repository methods for retrieving entity-specific sync data.
- Enhance offline logic for chapters, characters, locations, and world synchronization.
- Improve error handling across IPC handlers and repositories.
