Add offline mode logic for book, story, and world operations

- Integrate `OfflineContext` into book, story settings, and related components.
- Add conditional logic to toggle between server API requests and offline IPC handlers (`db:book:delete`, `db:book:story:get`, `db:location:all`, etc.).
- Refactor and update IPC handlers to accept structured data arguments for improved consistency (`data: object`).
- Ensure stricter typings in IPC handlers and frontend functions.
- Improve error handling and user feedback in both online and offline modes.
