ENG-10793.
Regarding "technical difficulties" described in the task, I decided to go with simple setStep() approach, which isn't the nicest possible but works well and doesn't require significant refactors. Any improvement suggestions appreciated though.

Depends on D14784

Test all types of alert, made sure a correct one is displayed:

• Throw in retrieveLatestBackupInfo, should show backupInfoFetchAlertDetails
• Throw inside useRestoreProtocol, should show userKeysRestoreErrorAlertDetails
• Throw inside restoreUserData (usingFullBackup enabled), should show userDataRestoreErrorAlertDetails
• Throw inside useV1Login, should show siwe or password login alert. Tested getting there in two ways:
  • By making latestBackupInfo = null;
  • By making useRestoreProtocol throwing use_v1_flow
