feat: GEOINT-Toolkit mit 6 neuen Features

- EXIF-Extraktion: Automatische GPS/Kamera/Zeitstempel-Analyse bei Bildupload
- Sonnenstand-Rechner: Azimut, Elevation, Schattenverhaeltnis fuer beliebige Position/Zeit
- Reverse Geolocation: Erweiterte VLM-Analyse mit Landschaftsmerkmalen (Vegetation, Architektur, Strassen, Schilder)
- Nachtlichter: NASA VIIRS Black Marble Layer
- Hoehenprofil: Interaktives 2-Punkte-Tool mit SVG-Chart und Sichtlinienanalyse
- Funkmasten: Mobilfunkinfrastruktur via Overpass (zoomabhaengig)

Backend: data_geoint.py (EXIF, Sun, Elevation, Celltowers)
Frontend: GEOINT Tools Section im Layer Panel
