Integrate offline logic for book creation and enhance synchronization

- Add offline handling to `AddNewBookForm` by updating `BooksSyncContext` with server-only and local-only book management.
- Refactor `guideTourDone` to check offline completion states via `localStorage`.
- Update and lock dependencies, including `@esbuild` and `@next`, to latest versions.
- Clean up unused session state updates in book creation logic.
