Add Gitea Actions workflows for CI/CD automation

- deploy-on-push.yml: Verify YAML, check SOPS encryption, notify on deployments
- milestone-release.yml: Auto-create releases on milestone tags

Triggers:
- deploy-on-push: On any push to main (apps/clusters changes)
- milestone-release: On git tag m*-*-complete
