Atlas: Tile-Proxy + Leaflet lokal — DSGVO-Sanierung fuer Kartendienste

Browse Source 
- Leaflet 1.9.4 (CSS + JS + 5 Marker-Images) lokal unter
  App/assets/vendor/leaflet/ statt via unpkg.com/Cloudflare
- Neuer PHP-Endpunkt App/php/tile-proxy.php mit Disk-Cache, liefert
  OSM- und CARTO-Kacheln serverseitig aus; Browser kontaktiert keinen
  Drittanbieter mehr
- Whitelist (osm, carto), Zoom 3-18, 30 Tage Browser-Cache, ETag +
  If-Modified-Since, sauberer User-Agent fuer OSM-Policy
- Cache-Pfad: APP_ROOT/data/tiles lokal, via .env TILE_CACHE_DIR
  auf Produktions-Volume /var/www/html/geograsim/data/tiles
- Heli (heli.php + heli-game.php), Logistik (logistik.php), Routes-
  Dev-Tool und admin-levels.html alle auf Proxy umgestellt
- Datenschutzerklaerung: alter Google-AdSense-Passus (falsch, nicht
  im Einsatz) entfernt, neuer Abschnitt zur serverseitigen
  Tile-Auslieferung mit Rechtsgrundlage Art. 6 Abs. 1 lit. f DSGVO
- .gitignore: App/data/tiles ausgeschlossen
- .env.example: TILE_CACHE_DIR + OpenAI/ElevenLabs dokumentiert
