fix(audio): device-reset false positive + stderr noise + i18n tooltip

- Device watcher requires 3 consecutive misses (~9 s) before triggering
  audio:device-reset, preventing false positives when ALSA temporarily
  hides a busy device from output_devices() enumeration
- Add stderr suppression to open_stream_for_device_and_rate (last source
  of ALSA terminal noise on Linux)
- Fix tooltip showing raw key 'common.refresh' — replaced with
  settings.audioOutputDeviceRefresh (added to all 8 locales)
- Device switch restarts track from beginning (no seek-back)
