fix(geoportal): simplified info panel, preserve basemap zoom, DXF export, intravilan outline

- Feature panel: simplified (NR_CAD/NR_CF/SIRUTA/Suprafata/Proprietari),
  aligned top-right under basemap switcher, click empty space to close
- Basemap switch: preserves zoom+center via viewStateRef + moveend listener
- DXF export: use -s_srs + -t_srs (not -a_srs + -t_srs which ogr2ogr rejects)
- Intravilan: double line (black outer + orange inner), z13+, no fill
- Parcel labels: cadastral_ref shown at z16+
- UAT z12: original geometry (no simplification)
- Removed MapLibre popup (only side panel)
