docs(CLAUDE.md): k8s-portal now GHA->ghcr, not a Woodpecker build

k8s-portal was the last in-cluster image builder. Its .woodpecker/k8s-portal.yml
was deleted; it now builds on GHA (build-k8s-portal.yml) -> PRIVATE ghcr, pulled
via the Kyverno ghcr-credentials allowlist and deployed by Keel. Fix the CI/CD
section: drop k8s-portal from the Woodpecker-pipelines list (stale), move it from
'already on GHA' to the infra-owned private-ghcr images, and add it to the
PRIVATE ghcr allowlist roster. Completes the no-local-builds migration.
