Add terms of use translations, sync detection, and refactor book components

- Introduced new translations for terms of use in French and English locales.
- Added sync status detection logic for books in `BookList` and `BookCard` components.
- Refactored `BookCard` to handle additional props and improve layout flexibility.
- Enhanced `TermsOfUse` component with complete localization support and refuse functionality.
- Updated data decryption logic in Rust services to handle optional fields and additional metadata consistently.
- Improved offline/online synchronization workflows with extended context properties.
