Daniel c0cb66ae3e feat(pe-guide): real lung recordings for normal/rhonchi/pleural-rub; ...

drop grunting + dead synth module

Three lung sounds that were Web-Audio syntheses now play real clinical
recordings sourced from the HLS-CMDS manikin dataset (MIT license):

- normal-vesicular.ogg
- rhonchi.ogg
- pleural-rub.ogg

Dropped expiratory grunting from the library entirely — no
openly-licensed clinical recording located across Wikimedia, Freesound
CC0, SPRSound, Pixabay, Internet Archive, or Littmann/EasyAuscultation
(all proprietary). Card is honest by omission rather than hiding a
synth behind a Play-only UI.

All seven remaining entries now use the same native <audio controls>
player (pause, seek, volume). The synth fallback branch in
renderSoundCard, the stopAllExcept synth reset loop, the script tag,
and the entire public/js/respiratorySounds.js (332 lines of Web Audio)
are removed since nothing references them anymore.
