Krzysztof kuhy Rudnicki 7aebf8e333 wake_alarm: louder + typeable + multi-fan
- Drop overrideredirect on the dismiss UI: on X11 it bypassed the WM and
  silently killed keyboard focus on the Entry, so the user could not type
  the dismiss code. -fullscreen + -topmost still cover the whole screen.
- Add _max_sink_volume() / _restore_sink_volume(): unmute the default
  PulseAudio/PipeWire sink and raise it to 100% at alarm start, restore
  the original volume + mute state on dismiss. This is the biggest audio
  lever — pcspkr is hardware-fixed and was already maxed.
- pcspkr: 3 back-to-back 1.5s beeps per cycle (was 1x 0.8s) at near-S16
  max amplitude.
- Fans script: control every NCT pwm[1-9] channel, persist per-channel
  pre-alarm state to /run/wake-alarm-fans.state so restore needs no args.
- Tests: 100% branch coverage on python_pkg/wake_alarm/ (140 passed).
