- Introduce `addToQueue` mechanism for syncing offline changes to the server.
- Add `isChapterContentExist` method and related existence checks in repositories.
- Consolidate data structures and streamline book, chapter, character, and guideline synchronization workflows.
- Encrypt additional character fields and adjust repository inserts for offline data.
