Improve the Firebase Account Module

Improve the Firebase Account Module

:recycle: Current situation & Problem

• Firebase includes some built-in password rules that we do not expose in the API
• We do not display localized error messages for Firebase errors
• The localization of the sign-up button is not correctly set
• The application does not recognize if, e.g., a user is deleted in the Firebase Emulator or on Firebase
• The application does not refresh its state when the user is logged in

Thank you to @jenlmoore for providing valuable feedback to the CardinalKit project!

:bulb: Proposed solution

• Includes a password rule in the UI (at least eight characters, no whitespaces)
• Adds localized descriptions for Firebase Errors
• Improves the logic in the account module to use the correct localization
• Automatically sets the user to nil and the account to be signed out if a user refresh token request did not succeed
• Adds further logic to refresh the application if a user is signed in
