Adds logs and analytics events with time measurements for the different stages of conference.init execution.

This way we can know from the logs what we are working with.

* feat(rn,screen-sharing) allow sharing the screen and camera on mobile

With the advancements in layer suspension it should now be ok to do.
Users can still mute the camera themselves if they so desire.

Having the camera enabled while in the background is a separate effort.

* feat(connection): Handles the new connection error CONFERENCE_REQUEST_FAILED.

Reloads when this fatal error occurs.

* chore(deps) lib-jitsi-meet@latest

https://github.com/jitsi/lib-jitsi-meet/compare/v1878.0.0+a7476b12...v1880.0.0+5d53ecdc

When we leave we see all participants leaving too, which triggers the
"recording has ended" sound for example, which is not desirable.

It was possible that join can be executed before conference.init have even started or we haven't reached the point ot create the initialGUMPromise. This was causing the following issues:
 - users stuck on the prejoin screen
 - participants join 2+ times in the call (we have been creating more than 1 local participants from a single page).

* feat(visitors): Uses metadata to save participants that were promoted.

* squash: fix comments.

* squash: fix comments.

* feat(mobile/background): use reducedUI only when app is not active and log appState changes

* enable precall test

* minor fixes

* update lang sort

* code review

The backend initializes them as all missing, this way we sync backend and UI.

By default, that feature is disabled.

Fixes an issue where we were showing cc button for visitors that does not have features in the token.

* fix(subtitles): Handle errors to revert to default state.

* fix(transcribing): Handle transcriber status changed.

Drops potential transcribers and hidden participant actions and handling. Expect ljm to detect transcriptions on and off.

* feat(transcriptions): Adds a notification if transcriber leaves abruptly.

* squash: Renames action.

* chore(deps) lib-jitsi-meet@latest

https://github.com/jitsi/lib-jitsi-meet/compare/v1869.0.0+5671c5d6...v1872.0.0+8940b5c9

Accessibility: keyboard navigation on the toolbar (Context menu)

* feat(follow-me): Adds option to limit it for recorder only.

* squash: Fix comments.

* squash: Fix comments.

* feat(visitors): Transcriptions for visitors.

* fix(transcriptions): Uses dial command to invite transcriber.

* fix(transcriptions,recording): Allows non moderators with features to dial, record or transcribe.

* sqaush: Make sure filtering works when only is a moderator.

It works now and without a token and no features, but being moderator.

* squash: Rename constant.

* squash: Toggles back captions button on error.

* squash: Fix comment.

* squash: Reverting back isLiveStreamingButtonVisible.

* squash: Fix imports.

* fix(rn,overlay) skip showing reload dialog while leaving the conference

Some parts of the ui still showed the setting for flipping the video, even if the flag indicated otherwise
Also fixes the case where setting a virtual background ignores the stored localFlipX setting

 - Move the styles from css to tss-react ones
 - Dynamic fontSize based on the visible area of the page
 - Remove the gaps in the background when a line is wrapped.
 - Change the text color to white.
 - Remove transparency.

We are fully using lodash-es now.

There is no point in ever setting lastN to anything other than 0 when in
the background because we are not rendering anything.

When in PiP mode, the app state is not background, which might have
deceived us into adding that check there way back when.

The latter supports tree-shaking and we don't need to embed the whole
500KB of lodash.

* feat(chat/polls/navigation): added ids for tests and removed some unused helpers

Fixes #14764.
