There is no need to skip the filmstrip, since it's not there.

We are using a safe area view now.

This is for devices without the home button.

The majority of the code is in the WASM file, the JS is just 9KB.
It's so little, in fact, that the performance hint for the main bundle didn't
have to be adjusted.

* feat: Drops filmStripOnly mode.

* squash: Let's make lint happy again.

* squash: Drop some css.

Makes the tiles consistent as the participant view is equally sized and the
avatar is always centered in the tile.

Moves the logic from all different places into single state
listener to combine all inputs into a single output.

Part of [1] replaces a `setPreferredVideoQuality` call with a
`setMaxReceiverVideoQuality` call. The change was part of a bigger
changeset that adds logic that tries to adjust the max based on reduced
ui turned on or off and allow to set prefered through the config.

However, by calling `setMaxReceiverVideoQuality` instead of
`setPreferredVideoQuality`, the new feature overrides the lower
resolution requested by tile-view earlier in some occasions.

This PR reverts back to using `setPreferredVideoQuality` instead of
`setMaxReceiverVideoQuality` as this achieves the same result without
overwriting the max set by the tile-view.

NOTE that this is a quick-fix and all the handling related to setting
the receive resolution will be reworked soon.

Showing the modal earlier is weird because it will be closed as soon as we
connect. Also, we don't know if we are going to be alone until we join.

Also, use the configured resolution to set it as the max received frame size.

Up until now we relied on implicit loading of middlewares and reducers, through
having imports in each feature's index.js.

This leads to many complex import cycles which result in (sometimes) hard to fix
bugs in addition to (often) breaking mobile because a web-only feature gets
imported on mobile too, thanks to the implicit loading.

This PR changes that to make the process explicit. Both middlewares and reducers
are imported in a single place, the app entrypoint. They have been divided into
3 categories: any, web and native, which represent each of the platforms
  respectively.

Ideally no feature should have an index.js exporting actions, action types and
components, but that's a larger ordeal, so this is just the first step in
getting there. In order to both set example and avoid large cycles the app
feature has been refactored to not have an idex.js itself.

The lobby feature adds the possibility to lock a meeting and only allow people in after virtually knocking and going through formal approval

Use a dimensions detecting root component. The Dimensions module does not
measure the app's view size, but the Window, which may not be the same, for
example on iOS when PiP is used.

Also refactor the aspect ratio wrap component since it can be taken directly
from the store.

Last, remove the use of DimensionsDetector on LargeVideo and TileView since they
occupy the full-screen anyway.

Fixes PiP mode on iOS.
