chore: Update the with-supabase example to use the Supabase Auth block

[ivasilov]

This PR updates the with-supabase template to better auth pages, Tailwind v4 and newest components.json for full compatibility with shadcn/ui.

The (auth-pages) folder has been removed. For auth, the template is now using the password based auth block from the Supabase UI Library which makes it easier to update it and keep it up-to-date.
