updated the upload functionality to handle large files and added a new image file

- Fix environment variable mismatch in create_default_user.py
- Now correctly uses ADMIN_USER and ADMIN_PASSWORD from docker-compose
- Maintains backward compatibility with DEFAULT_USER and DEFAULT_PASSWORD
- Change port mapping from 8880 to 80 for easier access
- Resolves login issues with admin user credentials
