feat(dashboard): 4-way roster (user/bot/voice/role), persistence, TTS all-emotions, layout

- 유저 등록/관리 search now has 4 types: 유저(non-bot members), 봇(bot members),
  통화방(current voice-channel members, bot flag enriched), 역할(roles — expandable
  to the members under each role; register the role OR a member under it).
- Persist settings to a JSON state store (WSAI_STATE_FILE, default
  ~/.config/wsai/state.json) so they survive a service/container restart:
  per-guild listen lists + bargeIn (BotControl), TTS base/overrides and the
  chosen STT/LLM models (Dashboard). Applied on voice-server startup before warm.
- TTS 감정 선택에 최상단 "전체변경 (모든 감정)" 추가: 적용하면 base를 그 값으로 세팅하고
  모든 per-emotion override를 지워 전 감정이 한 번에 그 값으로 말합니다.
- Move the component status bar (눈/시각/귀/LLM/입) above the bot bar.
