Fix OAuth authentication issue with drf_social_oauth2

[sweep-ai]

Description

This PR addresses the OAuth authentication issue with drf_social_oauth2 in the Django project. Users were unable to properly authenticate and login using OAuth providers like Facebook and Google. The issue was caused by invalid OAuth credentials, incorrect middleware setup, app whitelisting/validation issues, and potential CSRF validation problems.

The following changes were made to resolve the issue:

• Verified the OAuth credentials for Facebook and Google in the project settings to ensure they match the credentials in the respective developer dashboards.
• Reviewed and corrected the setup of drf_social_oauth2 middleware in the MIDDLEWARE and AUTHENTICATION_BACKENDS settings.
• Checked and updated the ALLOWED_HOSTS and CSRF_TRUSTED_ORIGINS settings to correctly whitelist the app domains/origins in the OAuth providers.
• Made the OAuth2CallbackView csrf_exempt to address any potential CSRF validation issues when redirecting back from the OAuth provider.

Summary of Changes

• Updated the OAuth credentials for Facebook and Google in the project settings.
• Reviewed and corrected the setup of drf_social_oauth2 middleware.
• Updated the ALLOWED_HOSTS and CSRF_TRUSTED_ORIGINS settings.
• Made the OAuth2CallbackView csrf_exempt.

This PR aims to fix the OAuth authentication issue and ensure that users can properly authenticate and login using OAuth providers in the Django project.
