📝 Description

Brief description of what this PR does.

This pull request introduces a complete authentication system using Supabase Auth, integrating both backend and frontend changes. It adds user registration and login endpoints, securely manages user profiles, and provides a user-friendly email confirmation flow. The update also includes necessary configuration, dependency updates, and a frontend confirmation page.

Backend: Authentication System Integration

• New authentication endpoints and logic:

  • Adds /auth/signup and /auth/login endpoints in auth.py that handle user registration and login via Supabase Auth, including error handling, local profile persistence, and rollback on failure.
  • Introduces corresponding Pydantic models for requests and responses in auth.py.
  • Registers the new authentication router in the main API (routes.py). [1] [2]

• Supabase integration and configuration:

  • Adds a singleton Supabase client in supabase.py using service role keys for admin operations.
  • Updates config.py to include Supabase and email redirect settings.

• Dependency updates for authentication:

  • Adds supabase==2.23.0 and its peer dependency websockets, and updates pydantic and psycopg2-binary versions to ensure compatibility.

Frontend: Email Confirmation Flow

• User-friendly confirmation page:
  • Adds confirm-email.html in the frontend, providing real-time feedback on email confirmation status and guidance for next steps, including extension integration hooks.
