* Create generic tooltip wrapper for mobile usability.
* Change overflow menu icon/font/padding sizes.
* Change overflow drawer expand icon.

* Remove pointless custom headers, fall back to ModalHeader instead.

* Bring back the filmstrip at small sizes but hide it.
* Change default maximum columns to 7.

Reverts a8b2e6ffb3

* Implement opening toolbar and participant overflows as drawers when below certain width.
* Fix dial-in copy button displaying incorrectly.

* Fix toolbox buttons not displaying properly when chat is open.
* Open chat in fullscreen dialog past custom thresholds when mobile/desktop toolbox would become unusable due to chat
* Remove mobile chat check when displaying toolbox

Due to how the filmstrip size if computed I don't think there is a good way to
animate the change in size, so just ignore the toolbar, it will be hidden soon
enough.

- Lower the inter-tile margin to 2px
- Remove the 100px top/bottom margin when the toolbar is hidden

* fix(Toolbox) Maintain overflow button visible at all times

* Make changes only on desktop browser

* feat: Drops filmStripOnly mode.

* squash: Let's make lint happy again.

* squash: Drop some css.

It has been `true` for a very long time.

* Fix layout
* Change background color & show image

The former is no longer actively maintained.

Fixes: https://github.com/jitsi/jitsi-meet/issues/6427

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.
---

* 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`.

* Adding responsive to jitsi logo, buttons and hiding some part of the interface
* moving media types thresholds to variables and apply only to screen
* hide chrome extension banner on very small view
* Hide filmstrip only on desktop narrow windows
