Update book handling and improve offline/online sync logic

- Enhanced the `BookProps` struct with updated field mappings for better API compatibility.
- Improved offline/online sync workflows in `BookList` by adding `localBook` property handling and new item count methods for segmented tracking of local/online items.
- Updated click handlers in `BookList` to fetch data based on connectivity state and prioritize local data when offline.
- Refactored the decryption and vault handling logic in Rust to remove obsolete legacy methods and standardize debug behavior.
- Introduced `ScribeShell` layout component with foundational logic for book/chapter syncing and offline queue handling.
- Added `init_panic_hook` to improve crash reporting during Rust app initialization.
