fix: stable scan display, accurate workflow preview, cladiri count

ROOT CAUSE: The cross-reference between immovable list and GIS layer
produces wildly different matchedCount on each scan (320, 430, 629, 433)
because the eTerra immovable/list API with inscrisCF=-1 returns
inconsistent results across calls. The GIS layer count (505) is stable.

SCAN DISPLAY — now uses only stable numbers:
- Header shows 'Layer GIS: 505 terenuri + X cladiri' (stable ArcGIS count)
- Shows 'Lista imobile: 2.717 (estimat ~2.212 fara geometrie)' using
  simple subtraction totalImmovables - remoteGisCount
- Cross-ref matchedCount kept internally for import logic, but NOT shown
  as the primary number — eliminates visual instability
- hasNoGeomParcels now uses estimated count (stable)

WORKFLOW PREVIEW — now accurate:
- Step 1: 'Sync GIS — descarca 505 terenuri + X cladiri' (separate counts)
  or 'skip (date proaspete in DB)' when fresh
- Step 2 (enrichment): Fixed 'deja imbogatite' bug when DB is empty.
  Now correctly computes what WILL be in DB after sync completes:
  geoAfterSync + noGeomAfterImport - localDbEnrichedComplete
- Steps 3-4 unchanged

CLADIRI COUNT:
- Scan now also fetches CLADIRI_ACTIVE layer count (lightweight, OBJECTID only)
- New field remoteCladiriCount in NoGeomScanResult
- Displayed in header and workflow step 1
- Non-fatal: if CLADIRI fetch fails, just shows 0
