The basic issue here, I think, was that the 'oneOnOne' observable flag and the 'onOnOneLayout' observable could become out of sync, as RxJS does *not* have atomicity guarantees. We can work around this by combining them into one observable.
This fixes a few different usability issues with the footer:
- When tapping one of the footer buttons, the footer would be dismissed rather than activating the button.
- When the footer was hidden, you could still tap the buttons.
- Interacting with controls in the footer would not reset the timer that hides it, leading to a feeling that the footer can disappear out from under you.

* Keep tiles in a stable order
This introduces a new layer of abstraction on top of MediaViewModel: TileViewModel, which gives us a place to store data relating to tiles rather than their media, and also generally makes it easier to reason about tiles as they move about the call layout. I have created a class called TileStore to keep track of these tiles.
This allows us to swap out the media shown on a tile as the spotlight speaker changes, and avoid moving tiles around unless they really need to jump between the visible/invisible regions of the layout.
* Don't throttle spotlight updates
Since we now assume that the spotlight and grid will be in sync (i.e. an active speaker in one will behave as an active speaker in the other), we don't want the spotlight to ever lag behind due to throttling. If this causes usability issues we should maybe look into making LiveKit's 'speaking' indicators less erratic first.
* Make layout shifts due to a change in speaker less surprising
Although we try now to avoid layout shifts due to the spotlight speaker changing wherever possible, a spotlight speaker coming from off screen can still trigger one. Let's shift the layout a bit more gracefully in this case.
* Improve the tile ordering tests
* Maximize the spotlight tile in portrait layout
* Tell tiles whether they're actually visible in a more timely manner
* Fix test
* Fix speaking indicators logic
* Improve readability of marbles
* Fix test case

Before you're connected to the SFU the local participant object will have the empty string as its ID. This changes to your actual ID once you've connected. Apparently I tried to fix this by forcing the local ID to always be the string 'local' but then I just forgot to use it correctly :)
This adds tests for a couple of the less trivial bits of code in CallViewModel. Testing them helped me uncover why focus switches still weren't being smooth! (It was because I was using RxJS's sample operator when I really wanted withLatestFrom.)
* Enable lint rules for Promise handling to discourage misuse of them.
Squashed all of Hugh's commits into one.

* Fix coverage reporting
Codecov hasn't been working recently because Vitest doesn't report coverage by default.
* Suppress some noisy log lines
Closes https://github.com/element-hq/element-call/issues/686
* Store test files alongside source files
This way we benefit from not having to maintain the same directory structure twice, and our linters etc. will actually lint test files by default.
* Stop using Vitest globals
Vitest provides globals primarily to make the transition from Jest more smooth. But importing its functions explicitly is considered a better pattern, and we have so few tests right now that it's trivial to migrate them all.
* Remove Storybook directory
We no longer use Storybook.
* Configure Codecov
Add a coverage gate for all new changes and disable its comments.
* upgrade vitest

* Stop sharing state observables when the view model is destroyed
By default, observables running with shareReplay will continue running forever even if there are no subscribers. We need to stop them when the view model is destroyed to avoid memory leaks and other unintuitive behavior.
* Hydrate the call view model in a less hacky way
This ensures that only a single view model is created per call, unlike the previous solution which would create extra view models in strict mode which it was unable to dispose of. The other way was invalid because React gives us no way to reliably dispose of a resource created in the render phase. This is essentially a memory leak fix.
* Add simple global controls to put the call in picture-in-picture mode
Our web and mobile apps (will) all support putting calls into a picture-in-picture mode. However, it'd be nice to have a way of doing this that's more explicit than a breakpoint, because PiP views could in theory get fairly large. Specifically, on mobile, we want a way to do this that can tell you whether the call is ongoing, and that works even without the widget API (because we support SPA calls in the Element X apps…)
To this end, I've created a simple global "controls" API on the window. Right now it only has methods for controlling the picture-in-picture state, but in theory we can expand it to also control mute states, which is current possible via the widget API only.
* Fix footer appearing in large PiP views
* Add a method for whether you can enter picture-in-picture mode
* Have the controls emit booleans directly
We've gotten feedback that it's distracting whenever the same video is shown in two places on screen. This fixes the spotlight case by showing only the avatar of anyone who is already visible in the spotlight. It also makes sense to hide the speaking indicators in spotlight layouts, I think, because this information is redundant to the spotlight tile.
This is because our layouts for flat windows are good at adapting to both small width and small height, while our layouts for narrow windows aren't so good at adapting to a small height.
If you were the only one in the call, you could get a broken-looking view in which the local tile is shown in the spotlight, and it's also shown in the PiP. This is redundant.
Due to an oversight of mine, 2440037639 actually removed the ability to see the one-on-one layout on mobile. This restores mobile one-on-one calls to working order and also avoids showing the spotlight tile unless there are more than a few participants.
If no one had spoken yet, we were still showing the local user in the spotlight. We should instead eagerly switch to showing an arbitrary remote participant in this case.
We've concluded that this behavior is actually more distracting than it is helpful, and we want to try out what it's like to just have the importance ordering and visual cues help you find who's speaking.
We're finding that if we reorder participants based on whether their mic is muted, this just creates a lot of distracting layout shifts. People who speak are automatically promoted into the speaker category, so there's little value in additionally caring about mute state.
Includes the mobile UX optimizations and the tweaks we've made to cut down on wasted space, but does not yet include the change to embed the spotlight tile within the grid.
