feat: implement proper relay response tracking for flight mode

- Use pool.publish() which returns individual relay responses
- Track which relays actually accepted the event (response.ok === true)
- Set isLocalOnly = true only when only local relays accepted the event
- This provides accurate flight mode detection based on actual publishing success
- Debug logging shows all relay responses for troubleshooting
