fix(parcel-sync): red parcel fill for buildings without legal docs

Instead of trying to color buildings directly (which requires an
unreliable cadastralRef join), the parcel itself gets a strong red fill
(opacity 0.45) when has_building=1 AND build_legal=0. Buildings sitting
on these parcels are visually on a red background.

Color scheme:
- Red fill: building without legal docs
- Light blue fill: building with legal
- Green fill: enriched, no building
- Yellow/amber fill: no enrichment

Removed broken gis_cladiri_status overlay. Simplified legend.
