Subject: [PATCH] Add registration functionality and update authentication
 views

- Implemented a new method in AuthController to display the registration form with localized labels and session error handling.
- Updated the login view to include a link for account creation.
- Enhanced the registration view with a link to the login form.
- Removed the obsolete showRegisterPage view to streamline the codebase.
