fix(geoportal-v2): siruta-aware parcela lookup (B1 round 2)

Previous fix searched by cadastralRef and picked the first
layerId-matching result. But cadastral refs collide across UATs:
"354686" exists in multiple counties. The Cluj-Napoca f9bf2ca4-...
parcel with full enrichment got passed over for a same-cad parcel
in another UAT that has no enrichment → panel rendered header +
"Caracteristici" with empty Intravilan, no "Date eTerra" section.

New server-side /api/gis/parcela/find?siruta&cad&layerId proxy:
- gisApi.search(cad) → filter by layerId → up to ~20 candidates
- For each candidate, parcela.get and check stored siruta
- Return the siruta-matching detail
- Fallback: first readable candidate (so the panel still has data
  even if siruta mismatch — better than empty)

Panel useEffect simplified: fast path = parcela.get by uuid when the
tile has one, slow path = parcela/find when not. 404 from find sets
the "not in central DB yet" empty state (user can hit Citește din
ANCPI to trigger orchestrator live-fetch).

Diagnostic logs: [gis-parcela-find] siruta=… cad=… layerId=…
candidates=N + per-hit "has_enrich=true keys=N" so we can tell from
container logs whether the right parcel resolved.
