bsncubed cd747aec40 Step 7.5b4a: player volume (Spotify app slider), applied after the ring

- player: volume 0..100 %, amplitude = (v/100)^3 (about -18 dB at 50 %,
  0 = mute), applied in the TX pull callback after the ring so a change
  is heard at once (the ring holds 4 s); ramped over one packet to avoid
  zipper noise. Spotify VOLUME events (0..65535) set it.
- Docs: pipeline order ring -> volume/gain, curve described.
- Verified from a Mac: RMS followed the slider immediately (100 % about
  -10 dBFS; steps to about -24.5 and -28 dBFS match the cubic curve for
  ~57 % / ~50 %); user: "sounds about right". Mute at 0 % not yet
  confirmed (check via /api/player/volume later).
