feat(parcel-sync): smart delta sync + fix HAS_BUILDING bug

- Fix: geoportal/enrich endpoint now looks up CLADIRI_ACTIVE from DB
  instead of hardcoding HAS_BUILDING=0, BUILD_LEGAL=0
- Quick-count check: skip OBJECTID comparison when remote==local count
- VALID_FROM delta: detect attribute changes on existing parcels and
  mark them for re-enrichment (catches spatial validity changes)
- Early bailout: skip all eTerra API calls when 0 features need enrichment
- Rolling doc check: probe 200 oldest-enriched parcels for new
  documentation activity (catches ownership/CF changes VALID_FROM misses)
- Targeted doc fetch: only fetch documentation for immovable PKs that
  actually need enrichment instead of all 10k+

Daily sync cost reduced from ~300+ API calls / 1-2h to ~6-10 calls / 10-15s.
