build(uhr): alarms, ringing, timer, stopwatch, world clock, bedtime, settings, widgets

- exact alarms via setAlarmClock, rescheduled on boot/time/zone change and app update
- foreground ringing service: alarm-stream audio with gradual volume, vibration,
  full-screen screen with slide to snooze/stop, silence-after, missed notification
- timers and stopwatch keep timestamps only; live countdown/chronometer notifications
- world clock offline from the time zone database (no network permission at all)
- own alarm tone, own analog face and launcher icon
- next-ring logic unit-tested incl. DST gaps and zone changes; screenshot tests
