Supabase Authentication

We can't query our store unless we know who the user is, so let's add that quickly.

Adding Auth

Follow the Supabase docs and add authentication to our app.

• Work in a branch, of course!
• Just using email link for now
• Replace our current auth and blow up some code!

We don't want Supabase code littered throughout the app so let's be sure to centralize it somewhere, in case we have to swerve later.

• Create an API store (?)
