diag(calls): add VoIP+push-token+ring-target logs; fix /call mount race
- AppDelegate: NSLog for didUpdate token, didInvalidate, didReceiveIncomingPush
- backend/push: log [push-token] register, [call-ring] receiver token-counts +
expo-push-fanout for android-fallback
- app/call.tsx: 250ms grace window before closeScreen on initial idle (fixes
'foreground call flashes briefly then disappears' race when dm.tsx
startCall set() hasn't propagated through useCallStore selector yet)
