Use global state for biometric prompt cancel storage (#8328)

* Fix error on close due to context differences in background

Desktop background does not have active user information. Also, we want to delete _all_ prompt cancelled data, not just that for the active user. Storing this on global and manipulating observables to active achieves this without needing any user information in the background.

* Remove potentially orphaned data

* Throw nice error if prompt cancelled used without active user

* Register migration
