Handle more call recording states

more call recording states are:
3 = Starting video recording
4 = Starting audio recording
5 = Recording failed

these actions were added:
- Show grey recording icon to moderators if recording is starting
- Show toast to moderators if recording failed
- Add system message for recording failed
