feat: Implement change password

[apomalyn]

As a user, if I'm authenticated with email/password (classic) I want to be able to change my password.

Requirements

• Implement a way to change the password of the user after confirming the identity of the user
• Have a way, in the settings to change my password
• This should only be accessible, if I'm connected with a classic method

What needs to be done

• Implement the UserRepository.updatePassword(String oldPassword, String newPassword) method. It should:
  • only be available if the user is using email/password as authentication method
  • confirm user authentication in Firebase (doc)
  • update the user password in Firebase (doc)
• Under authentication/change_password create a view and view-model
  • in the view:
  • static const routeName = "/authentication/update-password"
  • AppBar add a close button icon that go back to the previous screen when pressed
  • add 3 password fields:
    • Old password
    • New password
    • Confirm new password
  • add a Update password primary button
  • in the view-model, add a onChangePasswordPressed that:
    • validate that New password and Confirm new password field contents match
    • calls UserRepository.updatePassword method
    • on success, remove the page from the history and go back to the previous page
• In the settings/settings_view, under the "Account" section:
  • Add a "Change password" button
  • It should be visible only if the user is logged in using email/password method
  • On pressed, redirect to the new authentication/change_password page
• update the router to access the new view when /authentication/update-password is called

@apomalyn On est d'accord qu'on affiche cette option que si l'utilisateur est connecté via username/password ? Dans les autres cas, ce sont des services tiers qui les gèrent (apple/google), ou il n'y en a pas du tout. (anonyme)
