Fix device signing/companion ID, duplicate-device crash, background updates, and add level bubble to Live Activity

- Assign the shared development team to the widget extension and watch
  complication targets, and correct the watch app's companion bundle
  identifier so on-device installs succeed after the bundle ID rename
  to de.s0.fototeddy.VanAligneiOS.
- Guard against two ConfiguredDevices sharing a peripheralID (e.g. a
  double-tapped "Sichern"), which crashed BluetoothManager's
  Dictionary(uniqueKeysWithValues:) on launch.
- Keep Bluetooth running in the background while a Live Activity is
  active, so lock screen/CarPlay keep receiving fresh readings instead
  of freezing at the last value before backgrounding.
- Render the actual bubble-level graphic (not just a static icon) in
  the Live Activity's lock screen view and expanded Dynamic Island.
