add a way to perform local verification from the lockscreen, marked as a special form of verification in the Auditor results

It's important to mark this as done from the lockscreen.

Verifying a device from the lockscreen is very important, so people do not need to enter passwords into untrusted devices.
If this would be available directly after boot, it would be massive! (probably very hard to implement)
Other features (like clearing the database) should not be allowed from the lockscreen).
