feat(parcel-sync): fix click, color styling, UAT boundary cross-check

Click fix:
- Keep l-terenuri-fill visible but transparent (opacity 0) so it still
  catches click events for FeatureInfoPanel. Enrichment overlay renders
  underneath.

Color changes:
- No enrichment: amber/yellow fill (was light green)
- With enrichment: green fill
- Buildings: red fill = no legal docs, blue = legal, gray = unknown
- Parcel outline: red = building no legal, blue = building legal

Boundary cross-check (/api/geoportal/boundary-check?siruta=X):
- Finds "foreign" parcels: registered in other UATs but geometrically
  within this UAT boundary (orange dashed)
- Finds "edge" parcels: registered here but centroid outside boundary
  (purple dashed)
- Alert banner shows count, legend updated with mismatch indicators

Martin config: added gis_cladiri_status source with build_legal property.
Enrichment views: gis_cladiri_status now JOINs parent parcel's BUILD_LEGAL.

Requires: docker restart martin + POST /api/geoportal/setup-enrichment-views
