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.
