The "New Recovery Method" dialog would show if either the recovery method had
been changed or removed, but the dialog text didn't make much sense for the
removed case.
This adds a separate dialog customized for the removed case.
Fixes https://github.com/vector-im/riot-web/issues/8046.
This padding only one side made it impossible to center things in the dialog.
Since the dialog also has nice spacing without the padding, this change removes
it.
Fixes https://github.com/vector-im/riot-web/issues/7862.
Adds a New Recovery Method dialog which is shown when key backup fails because
of a version mismatch / version not found error.
The set up button in the dialog currently only marks a device as verified (via a
verification prompt) instead of the eventual restore and cross-sign flow, since
those pieces don't exist yet.
