As Element Call grows in complexity, it has become a pain point that our business logic remains so tightly coupled to the UI code. In particular, this has made testing difficult, and the complex semantics of React hooks are not a great match for arbitrary business logic. Here, I show the beginnings of what it would look like for us to adopt the MVVM pattern. I've created a CallViewModel and TileViewModel that expose their state to the UI as rxjs Observables, as well as a couple of helper functions for consuming view models in React code.
This should contain no user-visible changes, but we need to watch out for regressions particularly around focus switching and promotion of speakers, because this was the logic I chose to refactor first.

This also removes the use of the useLivekitRoom hook: we had reached
the point where the only thing it was actually doing was disconnecting,
so we now do that in the onClick handler for the leave button (I don't
think we need to disconnect on unmount?). It was otherwise just getting in
the way and causing tracks to be enabled/disabled when we didn't want them
to be. This also removes the need for the blockAudio code.

Previously it could be either undefined or type None which meant the
same thing: no need to have both, just make it required.
This also means we can move the line to set e2ee enabled into a more
sensible place rather than in the ActiveCall de-nulling wrapper.
It's unused ever since we switched to LiveKit, and we intend to use other telemetry mechanisms going forward to fill this debugging use case, so it can be removed as discussed in today's team meeting.
This upgrade came with a number of new lints that needed to be fixed across the code base. Primarily: explicit return types on functions, and explicit visibility modifiers on class members.
This attempts to converge all our modals on the new modal component while changing their designs as little as possible. This should reduce the bundle size a bit and make the app generally feel like it's converging on the new designs, even though individual modals still remain to be revamped.
We were manipulating the participant's mute state directly for some
reason, just for setting the mute state directly, which bypased the
mutestates hook.
Rather than the matrixRTC memberships. We're essentially trusting
LiveKit's view of weho is connected here, so we may as well include
the real names of anyone we don't think is a matrixRTC participant,
for whatever reason.
