[FEATURE] Implement Authentication Services

[albert118]

This is a two-parter. Both need to be completed to minimally support auth.

Custom Login Hook

To keep the login process consistent, we should create a useLogin hook. This hook should,

• handle the login state
• expose an isLoggedIn flag
• wrap the supabase auth signin logic
  • sign in should redirect to '/'
• expose a wrapper on the user session (we'll need ts support here)
• this session wrapper should contain the data as expected plus our own custom fields,
  • SID
  • role ('Student', 'Teacher')

Custom Sign-Up Hook

Like the above hook, but we'll also need to include our app's workflow here.

• handle the sign up state and wrap the supabase method
• call our API to generate a new contact entity

we can listen for the event,

see more on their docs

• return similar hooks and data as the login hook

Custom Sign Out Hook

etc. similar stuff - I haven't thought this one through as much but should be obvious

We'll most likely repeat similar patterns for the remaining workflows,

• forgot password
• get Session
• update user
