refactor: convert puppetserver compilers to deployment with configmap integration (#57)

- Convert StatefulSet to Deployment for better scaling flexibility
- Add initContainer to copy configmaps to shared RWX volume (10GB)
- Integrate puppetserver-compiler-config configmap for environment variables
- Configure configMapGenerator with stable names (disableNameSuffixHash)
- Update HPA to target Deployment instead of StatefulSet
- Simplify puppetboard SSL config to skip verification for internal connections
