perf: hide basemap boundaries, remove UAT layers, optimize Martin minzoom

Basemap cleanup (after map load):
- Hide OpenFreeMap boundary/admin layers (redundant with our UATs)
- Keep city/town place labels, remove village-level
- Hide our Martin UAT layers (not needed in ParcelSync — filtered by siruta)

Martin tile optimization:
- gis_terenuri_status minzoom: 10 → 13 (parcels not visible below 13)
- gis_cladiri_status minzoom: 12 → 14 (buildings not visible below 14)
- Prevents unnecessary tile fetches at low zoom levels

Applied to both ParcelSync Harta tab and Portal map.
Requires docker restart martin.
