Bump app version to 0.5.0 and implement offline mode support across components

- Added offline detection logic with `OfflineContext` to improve app functionality in offline scenarios.
- Integrated Tauri IPC functions to handle local tool settings and character attributes when offline.
- Refined indentation logic in `TextEditor` for better compatibility with WebKit engines.
- Removed unused `indent` property and related settings in editor components to simplify configuration.
- Updated locale files with improved translation consistency and parameterized placeholders.
