Add offline mode logic for chapter operations and refactor IPC handlers

- Integrate `OfflineContext` into `TextEditor` and `ScribeChapterComponent` to handle offline scenarios for chapter CRUD operations.
- Add conditional logic to switch between server API requests and offline IPC handlers (`db:chapter:add`, `db:chapter:remove`, `db:chapter:content:save`, `db:chapter:update`).
- Refactor and rename IPC handlers (`db:chapter:create` to `db:chapter:add`, `db:chapter:delete` to `db:chapter:remove`) for consistency.
- Update UI to disable certain actions when offline (e.g., GhostWriter button).
