feat: Link account skeleton

[apomalyn]

As a user, I want a simple way to create an account

Requirements

The Create account page should:

• support:
  • classic registration (email, password, confirmation)
  • Google Sign In
  • Apple Sign in (if not on an Android)
• should offer a way to go back to the previous screen

What needs to be done

• Create a create_account view and view-model under src/authentication/create
• the view should have:
  • static const routeName = "/authentication/link"
  • a back button on the AppBar to go back to the previous view
  • an email field
  • two password fields (one password, the second confirm password) with reveal (👁️) option
  • a Create account button
  • two icons button:
  • one with G from Google
  • one with apple (🍎) from Apple
• the view-model should:
  • validate the email field content using regex
  • validate that both password fields' contents are the same
  • when any sign-in with button or Create account button is pressed, redirect to Glossary tab
    • Note: create account page should be removed from the navigation history to avoid a user accidentally going there after entering the application
  • redirect to the previous screen if the back button is pressed
  • update the router to access the new view if /authentication/link is called

Design

Wireframe

⚠️ Be reminded that this is a wireframe, it shows the minimum required to fulfill the task but you can be creative for the rest of the page
