* feat: Hides prejoin screen on conference in progress event.

We enter the conference view as early as possible on conference in progress as the joined event can be late in a big conference.
Also, we show conference view only when joining is in progress, for example, the with the lobby enabled where we try to join but fail, we do not want to show the conference view for a fraction of a second before showing lobby screen.

* squash: Drops CONFERENCE_JOIN_IN_PROGRESS.

* squash: Updates ljm with the new JitsiConference event.

* squash: Adds some debugs to the github action.

Easier to catch problems with package-lock.json file.

* feat(prejoin) move invite to toolbar section

* feat(premeeting) redesign prejoin and lobby screens

* code review changes

* fix prejoin flicker and avatar id

* fix password error message and native lobby dialog close position

Also enable background selection while muted.

* feat(conference): Enable forced reload of client on bridge failure.
Force the client to reload when the bridge that is handling the media goes down.
This mitigates issues seen on the bridge because of a client re-joining the call with the same endpointId, BWE issues, etc.
This behavior is configurable through 'enableForcedReload' setting in config.js.
The client skips the pre-join page when the page reloads.

* squash: refactor the restart logic.

* squash: fix description

* squash: dispatch conferenceWillLeave action before reload.

* Adds a dropdown indicator which displays the status of the internet connection.
* It uses the same data as `https://network.callstats.io`.
* The algorithm for the strings displayed to the user is also the one used on `network.callstas.io`.

A user should not be forced to enter a display name if the lobby is not enabled
for the room.

* Add a checkbox for skipping the prejoin page on next use. (This is hidden for
now, until we also have a settings entry for it).
* Rework 'Join by Phone' buttons and add new overlay.
* Update the device status accordingly if there were errors while adding
devices.
* The input is filled with the display name if there was one previously used.
* Join the meeting on 'Enter' press.
