feat(parcel-sync): import eTerra immovables without geometry

- Add geometrySource field to GisFeature (NO_GEOMETRY marker)
- New no-geom-sync service: scan + import parcels missing from GIS layer
- Uses negative immovablePk as objectId to avoid @@unique collision
- New /api/eterra/no-geom-scan endpoint for counting
- Export-bundle: includeNoGeometry flag, imports before enrich
- CSV export: new HAS_GEOMETRY column (0/1)
- GPKG: still geometry-only (unchanged)
- UI: checkbox + scan button on Export tab
- Baza de Date tab: shows no-geometry counts per UAT
- db-summary API: includes noGeomCount per layer
