Ghost sign in

[MillerAdulu]

Description

Our mobile app only has social sign-in with Google. Google Play requires that you submit working credentials with the app to log in and review the app. Google requires every account to have 2FA setup, so it's unrealistic to hand them your personal account because the 2FA will fail. So this PR is to seed a dummy user on the app which the app can then use in Ghost mode to have the auth be circumvented on the app by long pressing the Fluttercon logo. This way they can log in to review the app and then once the app has been released, on the mobile end, we shall disable review mode so that normal users don't use this as a feature to bypass the login.
