feat: Add native TTS snapshot reconciliation and lifecycle management

- Added ReaderTtsPlaybackStore to manage TTS start requests with a maximum of 4 pending requests.
- Updated app configuration to use a production API URL.
- Enhanced BookmarkModel to infer type when not provided by the API for backward compatibility.
- Introduced methods in LocalStore for saving, loading, and clearing the last route path.
- Implemented syncProgress method in BookshelfNotifier to update reading progress and bookmarks from the server.
- Modified ReaderScreen to handle chapter navigation and TTS playback more effectively, including auto-start logic.
- Updated TtsPlayerWidget to accept additional parameters for chapter navigation.
- Enhanced TtsNotifier to handle new parameters for TTS requests and manage playback state.
- Improved SplashScreen to restore the last visited route after splash screen display.
