Add assertion (8) to internal-services-publish-no-public-dns. The external-dns
HelmRelease must declare annotationPrefix explicitly, and every
external-dns annotation in apps/, platform/, runbooks/ and catalog/render.py
must use that prefix. The v0.23.0 default-prefix change on 2026-11-07
ignored the controller: none, target and hostname annotations while
assertions (1)-(3) stayed green.
