fix(electron): correct SQLite IPC bridge implementation

- Replace generic execute method with specific IPC handlers
- Fix database operations by using proper IPC methods (createConnection, query, run, execute)
- Update type definitions to match actual IPC bridge interface
- Fix "Must provide statements" error by using correct method signatures

This change ensures proper communication between renderer and main processes
for SQLite operations, resolving database initialization and query issues.
