feat(geoportal-v2): swap refresh path to /parcel/enrich (deep-enrich)

gis-api session shipped PR3 (gis-api 09f1ab8 + gis-sync-orchestrator
0371d81): new POST /api/v1/parcel/enrich does the full eTerra
round-trip (searchImmovableByIdentifier → fetchDocumentationData
→ fetchImmovableParcelDetails) and merges NR_CF / ADRESA / PROPRIETARI
+ 20-plus fields into gis_core.GisFeature.enrichment with a 30-day
cache. Verified on 266888 + 328607 → 27 keys with full PII.

Wired in three places:

1. src/lib/gis-api-client.ts — gisApi.parcel.enrich({siruta,
   cadastralRef, force?}) thin wrapper.

2. src/app/api/gis/parcel/enrich/route.ts — architots-side proxy,
   matches the parcel/tech pattern (auth check → forward → bubble up
   GisApiError status codes).

3. src/modules/geoportal/v2/feature-info-panel.tsx — refreshFromAncpi
   now POSTs to /api/gis/parcel/enrich instead of /api/gis/parcel/tech.
   After the orchestrator returns, the panel re-fetches the canonical
   record via parcela.get (when uuid known) or parcela.find (when
   not), so it sees exactly what gis_core stores rather than the
   orchestrator response shape.

The existing auto-trigger (fires when detail has no NR_CF/ADRESA/
PROPRIETARI) now actually fills those fields. Subsequent clicks on the
same parcel hit gis-api's 30-day cache (5ms vs 1-2s live fetch).
