uhr: sleep sounds, sunrise alarm, reorder world clock, rename timers; 0.2.0

- own generated sleep sounds (rain, waves, brown noise) with sleep timer and fade-out
- sunrise: 15 min before the bedtime wake alarm, a full-screen screen brightens from ember to daylight
- world clock: long-press drag to reorder, with haptic ticks; order persists
- timers: tap the title to rename

 - **Ringing done right:** a full-screen screen over the lock screen with slide to snooze or stop, alarm-stream audio that gets louder gradually, vibration, automatic silence after a set time, and notifications for upcoming, snoozed and missed alarms. Volume keys can snooze or stop.
 - **No network permission at all.** World clock cities come from the system time zone database (names localised offline), sounds from the device, the app's own tone, or your own audio files.
 - **Also:** days and labels per alarm, pause until a date, skip the next ring, timers with ring progress and +1:00 that keep running in the background with a live countdown notification, stopwatch with fastest/slowest laps, analog or digital clock, wallpaper colours (Material You), three home-screen widgets (live digital clock, analog clock, next alarm).
-- **Coming next:** widget style options like Wetter, screensaver/night clock, sunrise alarm, sleep sounds, reordering world clocks.
+- **Bedtime extras:** own sleep sounds (rain, waves, deep noise) with a sleep timer that fades out, and a sunrise option that slowly brightens the screen 15 minutes before the wake-up alarm.
+- **Coming next:** widget style options like Wetter, screensaver/night clock.
