Add multi-language support and new repository methods for book synchronization

- Extend repository methods to handle API requests for fetching books, chapters, characters, and other entities with multilingual support (`lang: 'fr' | 'en'`).
- Add `uploadBookForSync` logic to consolidate and decrypt book data for synchronization.
- Refactor schema migration logic to remove console logs and streamline table recreation.
- Enhance error handling across database repositories and IPC methods.
