my-sea voice: volume-reactive equalizer glow + muted (--priRd/.fa-ban) state — TDD

Phase 5b of the my-sea voice batch. Resolves the Bug-B-vs-item-7 conflict per
user call 2026-05-29: a click while connected MUTES (leaving stays on BYE/NVM),
and the item-7 "--priRd/.fa-ban disconnected" visual maps onto the MUTED state.
Replaces Phase 3's 2x-pulse stand-in with a real Web-Audio equalizer.

- voice-mesh.js: an AnalyserNode taps each incoming peer stream (lazy
  AudioContext); `inputLevel()` returns the loudest current RMS (~0..1) across
  peers. Analysers torn down per-peer + on call end.
- voice-glow.js: the live-mic glow now resolves to — alone → `.voice-pulse`
  (steady 2s cadence); others connected → `.voice-eq`, whose `--voice-level`
  CSS var is fed each frame from inputLevel() via a self-stopping rAF loop;
  muted → `.voice-muted` modifier on either (recolor only). rAF cancelled on
  destroy.
- _burger.scss: `.voice-eq` box-shadow spread+alpha scale with `--voice-level`
  (no keyframe — audio drives it); `.voice-muted` recolors to --priRd (halo
  stays --ninUser) + flips the voice sub-btn icon to .fa-ban. Drops the unused
  `.voice-pulse--fast`.
- VoiceGlowSpec: +4 specs (equalizer swap, muted-alone, muted-with-others,
  unmute clears); VoiceMeshSpec: +1 (inputLevel 0 with no analysers). 438
  Jasmine specs green.

Live-verify on staging (audio can't be auto-tested): the equalizer reacting to
real speech + the muted/unmuted colour swap on a live call.
