Full details: Test Structure And Quality

Explanation
The prior assertion-message failure remains unresolved. The added
TestGetNamedCertificateCAsassertions at lines 6397 and 6400–6404 have no diagnostic messages: expected error, error absence, result length, CA-key presence, and non-empty CA data. The test uses a fake client and no waits, so timeout and resource-cleanup requirements do not apply.

- Line 2245: Update the `caCerts` extraction flow using
`ExtractCACertificatesFromChain` to handle a leaf-only `tls.crt`: validate and
use the Secret’s `ca.crt` when present, and report that the signer is
unavailable if neither source provides it before populating `root-ca`.
- Around line 2240-2241: Update the apierrors.IsNotFound handling in the
Secret-loading flow so a temporarily missing configured Secret cannot result in
publishing an incomplete CA bundle to root-ca; retain the previously populated
bundle or retry reconciliation without publishing the partial result.

- Line 50: Update the test certificate parsing around x509.ParseCertificate to
capture and check its error, failing the test immediately if parsing fails
instead of discarding the error.
Review comments at
@control-plane-operator/controllers/hostedcontrolplane/pki/ca.go:
- Line 144: Before appending a certificate to caCerts, validate it as a CA and
verify that it signs the preceding certificate using the appropriate x509
chain-verification APIs; skip certificates that do not form a valid signing
chain. Keep the existing PEM encoding and append behavior for validated
certificates.

When named certificates are configured for the KAS external endpoint via spec.configuration.apiServer.servingCerts.namedCertificates, the CA that signed those certificates was not included in the root-ca ConfigMap. This caused TLS verification failures for in-cluster service accounts and external tools connecting to the KAS external endpoint. Extract non-leaf CA certificates from named certificate Secret chains and include them in ReconcileRootCAConfigMap() so they propagate to the guest cluster's kube-root-ca.crt trust bundle.

What this PR does / why we need it:
When named certificates signed by an external CA are configured for the KAS external endpoint, the CA is not included in the
root-caConfigMap.This breaks TLS verification for in-cluster service accounts and external tools (e.g. ArgoCD) connecting to the KAS external endpoint, because
kube-root-ca.crtin the guest cluster only contains the HyperShift self-signed root CA.Fix
