fix: Updates docs and verification to halt joining process.

When returning the error and showing to user not allowed screen we were not completely halting the prejoin operation when token verification fails on room join and the token is valid in general.

Adapt to E2EE changes in lib-jitsi-meet. Notably:

---
    e2ee: introduce per-participant randomly generated keys

    This the second stage in our E2EE journey.

    Instead of using a single pre-shared passphrase for deriving the key used for
    E2EE, we now establish a secure E2EE communication channel amongst peers.

    This channel is implemented using libolm, using XMPP groupchat or JVB channels
    as the transport.

    Once the secure E2EE channel has been established each participant will generate
    a random 32 byte key and exchange it over this channel.

    Keys are rotated (well, just re-created at the moment) when a participant joins
    or leaves.

* feat: Allows jvb to control DTLS/SRTP protection profile.

* test: Adds dominant speaker change print for large in testing mode.

The amplitude-js dependency required a major bump.

This applies just to large view, not tile view.

When you join a conference that needs an authenticated moderator, as a guest, Jitsi Meet will continuously try and connect to the meeting every 5 seconds. Avoid starting the native call integration more than once.

It doesn't play well with webpack and it's babel config
and I couldn't find a way to make it work.

fix(prejoin): Auto focus display name input

Allows to adjust thresholds which control the video quality level
in the thumbnail view.

Changes the default behaviour to request the SD (360p) resolution only
when the thumbnails are at least 360 pixels tall and the height of
720 is required for the high quality level.

The thresholds can be configured with the 'videoQuality.minHeightForQualityLvl'
config property. Check the description in the config.js for more details.

feat(close3): Move readyToClose flow to the close page

* 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`.
