fix(server): register SystemDatabaseController and add PublicRoute decorator

- Register SystemDatabaseController in SystemDatabaseModule to expose /api/system_db endpoint
- Add PublicRoute decorator to bypass authentication for healthcheck endpoint
- Update ping() method to return { status: 'ok' } with HTTP 200

This fixes the Docker healthcheck that was failing with 404 Not Found errors.
