Neue Features: Satelliten-Orbits, Naturkatastrophen, Visual Modes

SATELLITEN (CelesTrak TLE):
- Raumstationen (ISS), GPS, Galileo, Wetter, Erdbeobachtung, Starlink
- Echtzeit-Positionsberechnung aus Kepler-Elementen (2s Update)
- Orbitbahnen als leuchtende Linien (Stationen, GPS, Galileo)
- Farbkodiert nach Gruppe (rot=Station, orange=GPS, blau=Galileo)

NATURKATASTROPHEN (NASA EONET):
- Waldbraende, Vulkane, Stuerme, Fluten, Erdrutsche, Eis
- Farbige Punkte mit Emoji-Labels
- Klick zeigt Details und Quellen

VISUAL MODES:
- STD: Standard-Ansicht
- NVG: Nachtsicht (gruener Monochrom-Filter)
- FLIR: Thermal-Ansicht (invertiert, Infrarot-Look)
- CRT: Retro-Monitor (Scanlines, Vignette)
