Update Docker configuration and composer.json scripts

The composer.json scripts have been updated to enhance the Docker setup process, enabling the application to automatically download core files and create a config file on project creation. Renamed environment variables in docker-compose.yml for consistency, added volume mapping for MySQL, preserving data across container restarts.
