Implement guest authentication with passphrases

[taesungh]

Add API routes and handlers for guest authentication. We currently don't have the frontend interface for guest login, so the authentication flow was tested manually with the FastAPI Swagger Docs and POST requests with curl.

Code Changes

• Import guest authentication code from last year
  • Import guest router and guest_auth component from last year's HackAtUCI/HackUCI-Site repository as is
• Fix EmailStr usage in test_guest_auth
• Replace references to hackuci with irvinehacks
• Use annotated FastAPI parameters in guest router
• Check for AUTH_KEY_SALT environment at runtime
  • Raise RuntimeError if AUTH_KEY_SALT environment variable is not provided to Vercel Serverless runtime
  • Reorganize environment variable usage and include note in API README
• Include guest router in app
• Clean up token expiration and fix unit test
• Temporarily replace guest token email with print
• Allow non-edu email in guest authentication flow
  • For IrvineHacks 2024, we are allowing high school students (18+) who would not have .edu email addresses
• Resolve Pydantic deprecation warning in GuestAuth
  • Replace parse_obj with model_validate

Deployment Changes

• Added AUTH_KEY_SALT to Vercel deployments
• Populated DB.settings.word_list with random word list

Testing

1. Run Docker compose for API
2. Add entries to the word list document through the Mongo Express interface at http://localhost:8081
3. Open the API docs at http://localhost:8000/docs
4. Try completing the guest authentication flow starting with /guest/login and then /guest/verify
   • The login token will be printed in the console instead of emailed
   • Note some of the requests are better done in curl to see the entire response headers
