Refactor authentication and session management

- Updated Dockerfile to use Python 3.13 and streamline system dependencies installation.
- Enhanced user session handling in auth.py, introducing a centralized method for retrieving the current user from the session.
- Removed deprecated auth routes and consolidated logic for user authentication and profile management.
- Improved error handling and user feedback in redeem.py and teams.py, ensuring users are redirected to login when not authenticated.
- Updated requirements.txt to include necessary packages for enhanced security and functionality.
- Added phpMyAdmin service to docker-compose for easier database management.
