Google Login Integration

Value Proposition

As a user,

I want to log in to the application using my Google account,

so that I can quickly and securely access the application without having to remember another username and password.

A "Login with Google" button is present on the login page along with "Github" account.
When the "Login with Google" button is clicked, the user is redirected to the Google OAuth consent screen.
Upon successful authentication, the user is redirected back to the application home page.
If it’s the first time the user is logging in with Google, after logging in they should start with creating a family and a member to proceed.
If the logged in user already has an associated family member, after logging in they have access to their family data.
