Modernize Docker Compose configuration

- Replace docker-compose.yml with compose.yaml (modern standard)
- Remove obsolete 'version' field (deprecated in Docker Compose)
- Remove development service configuration
- Add proper image tagging with skoszewski/jmespath-playground
- Keep build context for local development flexibility
- Simplify to production-only service configuration
