* 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.
* The prejoin page always displays the 'join without audio' option.
* The join button will be disabled if there is no input.
* Fix some CSS for the case when the user is not anonymous.
* 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.
