Authenticate users with Google Auth using Supabase OAuth feature

[Alankvuong]

As a user, I want to be able to login to the application using Google OAuth 2.0 authentication.

Guidelines:

• Only users registered under the Parking Reform Network domain (@parkingreform.org) should be able to login. For all other users, there should be an error that says their login is unauthorized.
• Use Google SSO. When users click this button, it will take them to a consent screen from Google where they have to approve the application to access their user information (username / password)
• Upon successful login, redirect them to the CRUD database.
