Queries the homeserver for PSTN protocol support, and if found,
the add-room button on the DM rooms list section opens a context
menu instead with a 'dial pad' option as well as the current 'start chat'
dialog. Entering a number into this and pressing dial performs
a thirdparty user query for the given string and starts a DM with that
user.
* Add bottom margin on PiP view
* Remove avatar blurring & pause icon for held calls
* Change background of incoming call box to match PiP view
* Put drop shadow & border radius on PiP view & incoming call box
rather than the CallContainer they're in (so they each have their own
drop shadow / rounded corners).
* Add margin between incoming call box and PiP view
Also hide video mute button on voice calls (awaiting clarification from design)
and fix mute keyboard shortcuts by moving them out of roomview & into
callview.
* Buttons on the main view will disappear after 1 second of the user
not moving the mouse over the call view.
* PIP view has no buttons, and not moveable yet
* No call status in room view yet
* Room status bar is still there currently
Currently just by adding /holdcall and /unholdcall slash commands
The only place the hold status of the call is currently represented
is when the call is a voice call and you're viewing a different room:
it's not wired up when you're viewing the room because that currently
uses the room status bar which it won't do with the new UI.
Also convert VideoFeed to typescript, and remove videoview because
it essentially just managed the fullscreen functionality, but we'll
want and 'on hold' representation (and probably chrome for hagnup etc)
in the fullscreen UI too, so let's just make CallView the thing that
gets fullscreened.
* Similar sizing
* Fix pointers so the jitsi widget doesn't feel clickable when it's not
* We might want to introduce click-to-visit-room for the Jitsi widget (like the 1:1 call), however the Jitsi widget has many more controls to worry about
* Remove the menu bar from the widget to avoid accidents
