Implement Google and GitHub OAuth Authentication in Backend

[akshayw1]

Is your feature request related to a problem? Please describe.
Currently, the authentication system relies only on manual email registration, which can be cumbersome for users who prefer quick login options via Google or GitHub. This limitation may discourage potential users who expect OAuth integration for a streamlined and secure login experience.

Describe the solution you'd like
Implement backend support for Google and GitHub OAuth authentication. This would involve setting up OAuth endpoints to handle user login and registration, redirecting to the respective provider's authorization page, and handling the token exchange. After successful authentication, our backend should store essential user details (e.g., unique ID, email, profile picture URL) and create a new user entry if one does not already exist.

Describe alternatives you've considered

1. Adding only Google OAuth initially, with the possibility of adding other providers in the future.
2. Implementing a custom session management system to link OAuth logins with existing email-based accounts.

Additional notes:
This feature will provide users with a more secure and convenient login option, improving user experience and potentially increasing user retention. For GitHub OAuth, ensure that necessary scopes are requested to allow retrieval of basic profile information.
