* fix(dial-in): allow scroll on dial in info page

* squash: some more tweaks for flexible sizing

Very likely I broke something subtle and I'm prepared to fix it.

* feat(recording): show the YouTube live stream URL

- From the start live stream dialog, push up the broadcast ID
  of the chosen broadcast. It is assumed the ID can be used to
  create the YouTube link.
- Listen for lib-jitsi-meet to emit updates of the known live
  stream URL, shove it into redux, and have InfoDialog display
  it.

* ref(info): pass in dial in and live stream url

Passing these values in should trigger AtlasKit InlineDialog
to re-render and reposition itself.

* ref(info): use conference existence as trigger for autoshowing dialog

* feat(info): add live stream link to invite copy

* Revert "ref(info): use conference existence as trigger for autoshowing dialog"

This reverts commit 1072102267.

* hidden -> url

* _onClickHiddenURL -> _onClickURLText

The call url is an anchor element so that right clicking it
can bring up the copy link option in the context menu.
Clicking on it does a no-op so the anchor was colored to
look like plain text. Hovering over it right now makes it
look like an anchor due to some atlaskit color, so supress
the coloring.

* fix(info): bold info labels

* fix(info): do not truncate url

* feat(info): show only during a lonely call

* feat(info): new dialog design

- Add display of a dial in number.
- Add a static page to show a full list of dial in numbers.
- Add password management.
- Invite modal will be changed soon to remove password and
  dial-in.
