fix: georef_status Server-Default + Admin editierbar

- Ingestor SQLAlchemy-Model: georef_status mit server_default='pending'
- DB-Spalte: DEFAULT 'pending' gesetzt → Ingestor-INSERTs schlagen nicht mehr fehl
- Admin: georef_status, georef_method, georef_error, locations editierbar (nicht mehr readonly)
- Ermöglicht manuelle Georeferenzierung im Django Admin
