feat(parcel-sync): include no-geometry rows in Magic GPKG + HAS_GEOMETRY column

- Magic GPKG (terenuri_magic.gpkg) now contains ALL records:
  rows with geometry render as polygons, rows without have null geom
  but still carry all attribute/enrichment data (QGIS shows them fine)
- Added HAS_GEOMETRY column to Magic GPKG fields (0 or 1)
- GPKG builder now supports includeNullGeometry option: splits features
  into spatial-first (creates table), then appends null-geom rows
- Base terenuri.gpkg / cladiri.gpkg unchanged (spatial only)
- CSV still has all records as before
- GeoJsonFeature type now allows null geometry
- Reproject: null geometry guard added
- UI text updated: no longer says 'Nu apar in GPKG'
