Display calls like phone calls for DMs

### Your use case

#### What would you like to do?
In Element Classic, calls were displayed analogous to phone calls as they're normally displayed on the phone UIs: they show who called and the status of the call (e.g. missed). It would even show a Call Back button in the missed call case. Element X doesn't do that and shows the same UI for all calls. I think the current UI seems more driven to make sense for group calls, but for DMs, it's nice having this info.

#### Why would you like to do it?
I'm most interested in knowing who called whom and also if a call was missed. I also like knowing how long the calls were (also displayed in Element Classic), which is also standard for displaying calls in the Phone/Calls app usually on smartphones.

#### How would you like to achieve it?
The UI was pretty good in Element Classic, so copying it would work.
