build(docker): remove environment variables from Dockerfile and docker-compose

Removes LANGFLOW_HOST, LANGFLOW_PORT from Dockerfile and simplifies docker-compose.yml by removing redundant environment variables (LANGFLOW_DATABASE_URL, LANGFLOW_AUTO_LOGING, LANGFLOW_LOG_LEVEL, HTTP_PROXY, HTTPS_PROXY, NO_PROXY). These values are now managed via the .env file for better configuration management.
