5 neue Layer: Militaerflug, Seekabel, Infrastruktur, ISS Tracker

MILITAERFLUGVERKEHR (adsb.lol /v2/mil):
- ~254 Militaerflugzeuge weltweit in Echtzeit (rot)
- Callsign-Labels bei Zoom (RCH=USAF, GAF=Luftwaffe etc.)
- Klick zeigt: Callsign, Registration, Typ, Hoehe, Squawk
- 20s Refresh

SEEKABEL (TeleGeography):
- Untersee-Glasfaserkabel als cyan-Linien auf dem Globus
- ~500+ internationale Kabelverbindungen
- Geopolitisch relevant (Sabotage, Abhoerung)

INFRASTRUKTUR (OpenStreetMap Overpass):
- 348 Kernkraftwerke weltweit (gelb mit Orange-Rand)
- Militaerflughaefen (rot)
- Labels bei Zoom (<500km)
- 24h Cache (statische Daten)

ISS TRACKER (Open-Notify API):
- Echtzeit-Position der ISS (roter Punkt, 420km Hoehe)
- 5s Refresh, prominentes Label
- Klick zeigt Details
