* Create state for biometric client key halves

* Move enc string util to central utils

* Provide biometric state through service

* Use biometric state to track client key half

* Create migration for client key half

* Ensure client key half is removed on logout

* Remove account data for client key half

* Remove unnecessary key definition likes

* Remove moved state from account

* Fix null-conditional operator failure

* Simplify migration

* Remove lame test

* Fix test type

* Add migrator

We don't need to determine platform in desktop background, it can be done in the UI at any time.

* Fix merge

* Use platform utils to identify OS desktop type
