Implements GitHub OAuth integration for user authentication, adding a 'Login with GitHub' button and necessary backend support.

Web Interface Updates: Adds a 'Login with GitHub' button in TARS/surfaces/web/web.py and implements the OAuth flow to authenticate users with GitHub. It also includes logic to generate and store a CSRF protection state in the session and redirects users to GitHub for authentication.
API Enhancements: Introduces a new API endpoint in TARS/surfaces/API/api.py to handle the GitHub OAuth callback. This includes extracting the GitHub access token from the callback request, a placeholder for exchanging the code for an access token, and another placeholder for validating the access token and retrieving user information.
Configuration Management: Updates TARS/config/config.py to load GitHub OAuth app secrets (client ID and client secret) from the .env file, ensuring secure handling of sensitive information.

Sweep: PR Review

TARS/config/config.py

A new GitHubOAuthSettings class was added to manage GitHub OAuth settings, and an instance of this class was initialized.

Potential Issues

Sweep isn't 100% sure if the following are issues or not but they may be worth taking a look at.

The GitHubOAuthSettings class directly fetches environment variables using os.getenv instead of using the BaseConfig mechanism, which could lead to inconsistencies in how environment variables are managed across different settings classes.

TARS/surfaces/API/api.py

The changes introduce a new GitHub OAuth callback endpoint and necessary imports for handling OAuth authentication.

Sweep Found These Issues

The exchange_code_for_access_token function is a placeholder and does not actually implement the code exchange process, which will cause the OAuth flow to fail.
The validate_access_token_and_retrieve_user_info function is a placeholder and does not actually validate the access token or retrieve user information, which will cause the OAuth flow to fail.

TARS/surfaces/web/web.py

The changes reorganize import statements for better readability and add GitHub OAuth integration for user authentication.

Sweep Found These Issues

The use of st.experimental_rerun(url) on line 65 is incorrect as st.experimental_rerun does not accept any arguments and should be replaced with st.experimental_set_query_params or another appropriate method to handle redirection.
The redirect_uri on line 59 is hardcoded to 'http://localhost:8501/auth', which may not work in production environments and should be configurable.

Potential Issues

Sweep isn't 100% sure if the following are issues or not but they may be worth taking a look at.

The client_id on line 58 is fetched using os.getenv('GITHUB_CLIENT_ID') without handling the case where the environment variable might not be set, which could lead to a runtime error.

Implements GitHub OAuth integration for user authentication in the TARS application.

Configures GitHub OAuth settings: Adds GitHubOAuthSettings class in config.py to initialize GitHub OAuth settings using environment variables.
Implements OAuth callback endpoint: Adds a new endpoint /auth/github/callback in api.py to handle GitHub OAuth callbacks. This includes extracting the code and state from the callback request, exchanging the code for an access token, validating the access token, and retrieving user information.
OAuth utility functions: Replaces placeholder methods with actual implementations for exchanging the GitHub OAuth code for an access token (exchange_code_for_access_token) and for validating the access token and retrieving user information (validate_access_token_and_retrieve_user_info) using HTTP requests to GitHub's API.
Web interface enhancements: Modifies web.py to include a GitHub login button, handle the OAuth flow, and display authenticated user information after successful login. This includes generating a random state value for CSRF protection and preparing the GitHub OAuth URL for redirection.
