[Login] Review the login error handling

[alexjba]

This is a follow-up task to address the concerns identified in #13046.

The fix for the issue above was to switch to regular login whenever the biometric login fails in status-go. The rationale is that the user cannot mitigate this error from the biometrics login screen and the regular login has been designed to show the errors description.

@benjthayer We'll need your help here. Is this flow correct?

Feel free to update or close the task.

          The flow here is not clear for me.

From the issue description I understand that the problem here is invisible error message in case of failed biometric login. But nothing about automatic switch to password mode. Isn't it confusing for potential user to switch automatically with no chance to do another attempt with biometrics and only optionally explicitly switch to password mode by clicking button?
