feat(geoportal): PMTiles for terenuri/cladiri overview + cache warming + cleanup

- Extend PMTiles to include simplified terenuri (5m tolerance) and cladiri (3m)
- map-viewer: terenuri z13 from PMTiles, z14+ from Martin (live detail)
- map-viewer: cladiri z14 from PMTiles, z15+ from Martin
- Martin sources start at higher minzoom when PMTiles active (less DB load)
- Add warm-tile-cache.sh: pre-populate nginx cache for major cities
- Rebuild script now includes cache warming step after PMTiles upload
- Remove deprecated docker-compose version: "3.8"
