feat(parcel-sync): search by cadastral number with full details

Search tab now uses eTerra application API (same as the web UI):

- POST /api/eterra/search queries /api/immovable/list with exact
  identifierDetails filter + /api/documentation/data for full details
- Returns: nr cad, nr CF, CF vechi, nr topo, suprafata, intravilan,
  categorii folosinta, adresa, proprietari, solicitant
- Automatic workspace (county) resolution from SIRUTA with cache
- Support for multiple cadastral numbers (comma separated)

UI changes:
- Detail cards instead of flat ArcGIS feature table
- Copy details to clipboard button per parcel
- Add parcels to list + CSV export
- Search list with summary table + CSV download
- No more layer filter or pagination (not needed for app API)

New EterraClient methods:
- searchImmovableByIdentifier (exact cadaster lookup)
- fetchCounties / fetchAdminUnitsByCounty (workspace resolution)
