ci: switch from Kubernetes to Podman for local deployment

- Update Dockerfile to use fully qualified composer image name
- Replace kubectl commands with podman kube play/down in Makefile
- Change from Kubernetes Secret to ConfigMap for environment variables
- Set imagePullPolicy to Never and use localhost/ prefix for local images
- Reduce replica count to 1 for local development
- Add stop target to Makefile for easier cleanup
