Show on hold in management screen for conference call.

Do the following when a participant is on hold:
- Add "On hold • " in front of the number
- Gray out avatar and text (contact name & number)

Notice:
We only have the on hold state information for VoLTE conference call and IMS conference call. So the change only works for them (not for GSM/CDMA conference call).
