fix: SQLite plugin initialization in Electron main process

- Changed from direct plugin usage to SQLiteConnection pattern
- Matches how platform services use the SQLite plugin
- Removed handle() method dependency
- Added proper method routing in IPC handler

The app now launches without initialization errors. Next steps:
- Test actual SQLite operations (createConnection, query, etc.)
- Verify database creation and access
- Add error handling for database operations
