Remove DataService and OfflineDataService, refactor book and character operations to use streamlined handlers in LocalSystem
- Delete `data.service.ts` and `offline-data.service.ts`, consolidating functionality into `LocalSystem`. - Refactor book, character, and conversation operations to adopt unified, multilingual, and session-enabled IPC handlers in `LocalSystem`. - Simplify redundant legacy methods, enhancing maintainability and consistency.
