fix(web): blindtest sound, hidden vote status, authoritative tracks, quiz input

From friends playtest feedback:
- blindtest "who added it?" (and mixed): hide the per-player vote status — the
  contributor never validates, which gave them away
- blindtest sound: set YT player `origin`/`enablejsapi` (fixes the postMessage
  origin warning) and add a per-game "Activer le son" gesture for non-DJ
  (browsers block audible autoplay without a user gesture)
- track list: render each player's own tracks from a server-sent, authoritative
  blindtest:myTracks event (emitted on submit/remove/reconnect) instead of local
  state that desynced on remount — fixes the "3/3 but only 2 shown" case
- quiz: reset the free-answer input between questions (was pre-filled with the
  previous answer)

Verified e2e: myTracks emitted on submit + reconnect.
