Refactor character, chapter, and story components to support offline mode

- Add `OfflineContext` and `BookContext` to components for offline state management.
- Introduce conditional logic to toggle between server API requests and offline IPC handlers for CRUD operations.
- Refine `TextEditor`, `DraftCompanion`, and other components to disable actions or features unavailable in offline mode.
- Improve error handling and user feedback in both online and offline scenarios.
