Jakub 6399df1f4a fix: improve buzzer volume control on nRF52 ...

- Use inverted PWM polarity (0x8000) with PCT {2,5,12,25,50} giving
  ~6-8 dB perceptual steps (-24/-16/-9/-3/0 dB) vs the original
  uneven steps where levels 4 and 5 were only 1 dB apart
- Guard against cmp=0 truncation in both _nrfStartPwm and applyVolume:
  at level 1 with high notes (freq > ~2.5 kHz) integer math gives
  cmp=0 which with inverted polarity means 100% HIGH → complete silence
- Change volume preview note from C5 (523 Hz) to C6 (1047 Hz) to better
  match the piezo resonant frequency range and actual notification sounds
