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.
* Update dependency @livekit/components-react to v1.4.1
* patch to match new lk api

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.
To track media devices, we were previously relying on a combination of LiveKit's useMediaDeviceSelect hook, and an object called UserChoices. Device settings should be accessible from outside a call, but the latter hook should only be used with a room or set of preview tracks, so it couldn't be raised to the app's top level. I also felt that the UserChoices code was hard to follow due to lack of clear ownership of the object.
To bring clarity to media device handling and allow device settings to be shown outside a call, I refactored these things into a single MediaDevicesContext which is instantiated at the top level of the app. Then, I had to manually sync LiveKit's device state with whatever is present in the context. This refactoring ended up fixing a couple other bugs with device handling along the way.
