Rene: Funkloecher + Routen waren nach 'Alles loeschen' weiter weg.
- Funkloch-Regionen jetzt im Keep-Set (geloescht wird NUR Manuelles);
Zonen behalten ihren Fuellstatus (Komplett-Wipe setzt weiter zurueck)
- Korridor-Migration beim Loeschen: keepTracks=[{name,track}] schreibt
Tracks in Alt-Eintraege ohne r.track (Bestand vor v1236) bzw. legt
fehlende Korridor-Regionen an — kein Warten auf Self-Healing
- clear() liefert Summary; Toast zeigt 'behalten: Standort, X Routen,
Y Funkloch-Gebiete' — Diagnose-Sichtbarkeit fuer Geraetetests
