Add SSL configuration and build workflow

- Add build-image.yml workflow for automated builds to GHCR
- Add SSL certificates and domain configuration for HTTPS
- Update services to use ghcr.io/ghndrx/k8s-game-2048:latest with imagePullPolicy: Always
- Configure Kourier for SSL redirect and domain claims
- Enable HTTPS for all environments: dev, staging, prod
- Add domain mappings with TLS configuration
- Add setup-ssl.sh script for easy deployment
