fix(frontend): refresh WS token after connection failures and handle AI/repo events

Clear wsToken on auth-related close codes (3000-4999), connection
timeout, and after 3 consecutive reconnect failures so the next connect
attempt fetches a fresh token. Add onRoomAiUpdated and onRepoChanged
callbacks that re-fetch AI configs and repo list when pushed via WS.
Fix AI member list to never display raw UUID.
