fix(voice): live connection state instead of static SSR snapshot

- VoiceView now reads connected/activeChannelName from useVoiceStatus
  (SWR live, invalidated by connect/disconnect) instead of initialStatus
- Seed useSpeakers from live status.activeSpeakers
- Add 4s refreshInterval to useVoiceStatus so state converges
(tsc clean, next build green)
