🐳 Update to modern Docker Compose v2 and fix GitHub Actions CI/CD

- Update docker-compose.yml to use modern 'docker compose' syntax (v2)
- Fix GitHub Actions Docker login to use GitHub Container Registry (ghcr.io)
- Add comprehensive GitHub repository settings documentation
- Add alternative CI/CD workflow without Docker push requirement
- Update package.json scripts for modern Docker commands
- Add Docker security scanning and metadata extraction
- Add repository permissions configuration for GitHub Actions
- Update Docker documentation with modern practices

This addresses the Docker login issues and modernizes the deployment
process while providing fallback options for CI/CD implementation.
