Integrate offline support and improve error handling across app

- Add `OfflineContext` to manage offline state and interactions within components.
- Refactor session logic in `ScribeControllerBar` and `page.tsx` to handle offline scenarios (e.g., check connectivity before enabling GPT features).
- Enhance offline PIN setup and verification with better flow and error messaging.
- Optimize database IPC handlers to initialize and sync data in offline mode.
- Refactor code to clean up redundant logs and ensure stricter typings.
- Improve consistency and structure in handling online and offline operations for smoother user experience.
