Restore the prescribed reconciliation order.

reconcileSecrets now runs before deployment reconciliation. The required sequence places reconcileSecrets after reconcileConfigMaps. Restore that sequence, or update the repository rule with an explicit exception.

As per coding guidelines, “The reconcile loop must follow this order: fetch CR, apply runtime defaults, reconcile RBAC, reconcile Controller Deployment, reconcile Router Deployments, reconcile Services/networking, reconcile ConfigMaps, reconcile Secrets, update status.”

Prevent telemetry TLS misconfiguration.

When an external IssuerRef has no CABundle, resolveTelemetryCA returns ("", nil), and buildConfig omits telemetry.certificate. The telemetry Deployment does not mount its cert-manager Secret, so the telemetry service uses a self-signed certificate that exporters cannot verify. Mount and configure the issued certificate, or fail reconciliation when no matching CA is available. Add an envtest for this path.

cert-manager telemetry never silently produces an empty telemetry.certificate

Secret is mounted and configured, or return a reconciliation error when no
matching CA is available. Add an envtest covering the missing-CABundle path and
verify TLS configuration is not emitted with an unusable CA.

Restart telemetry pods after TLS Secret rotation.

TelemetryService.Start loads EXTERNAL_CERT_PEM and EXTERNAL_KEY_PEM once through LoadTLSCredentials. A running server can keep the old certificate after the mounted Secret changes. Add the TLS Secret content hash to the telemetry Pod template and add a renewal regression test.
