Quick Cleanup for the Login and Register Pages

In this lesson, we'll streamline our authentication logic by organizing the code more efficiently. Instead of having separate auth functions scattered across different components, we'll create a dedicated file called supaAuth.ts in the utils directory to centralize the authentication logic.

We'll start by moving the registration function into this file, allowing it to handle the user sign-up and profile creation. Next, we’ll define TypeScript interfaces for form data to ensure type safety for both the register and login functions.

By cleaning up the code this way, our components stay lean and the auth logic remains reusable and maintainable.
