fix(tests): fix label/annotation paths and add missing templates

- Replace escaped dot notation (app\.kubernetes\.io/name) with bracket notation (["app.kubernetes.io/name"])
- Add missing templates to test suites (service.yaml, ingress.yaml, httpRoute.yaml, serviceaccount.yaml, persistentVolumeClaim.yaml)
- This fixes 40+ test failures related to unknown paths in labels and annotations

Test progress: 535/603 passing (89%), up from 495/603 (82%)
