Persist conversation history to disk + mount workers under gateway appdata

- TS worker saves/loads messages to {stateRoot}/conversation.json
- Saves after user message, assistant response, and session reset
- Loads on engine construction (survives container restarts)
- Add CLAW_GATEWAY_WORKER_HOST_STATE_ROOT and
  CLAW_GATEWAY_WORKER_HOST_WORKSPACE_ROOT to Unraid XML, defaulting
  to /mnt/user/appdata/claw-telegram-gateway/workers
