feat(geoportal): enrichment API + CF download + bulk enrichment

New API endpoints:
- POST /api/geoportal/enrich — enriches all parcels for a SIRUTA,
  skips already-enriched, persists in GisFeature.enrichment column
- GET /api/geoportal/cf-status?nrCad=... — checks if CF extract exists,
  returns download URL if available

Feature panel:
- No enrichment: "Enrichment" button (triggers eTerra sync for UAT)
- Has enrichment + CF available: "Descarca CF" button (direct download)
- Has enrichment + no CF: "Comanda CF" button (link to ePay tab)
- Copy button always visible
- After enrichment completes, panel auto-reloads data

Selection toolbar:
- Bulk "Enrichment" button for selected parcels (per unique SIRUTA)
