Tenant Kubernetes clusters had no way to configure the kube-apiserver authentication through the app values: no knob for OIDC, the structured AuthenticationConfiguration, extra apiserver flags, or extra volumes. The only workaround was patching the underlying KamajiControlPlane out-of-band, which is invisible to GitOps and lost on recreation. Add three opt-in fields under controlPlane.apiServer, all empty by default so existing clusters render unchanged: - extraArgs -> KamajiControlPlane spec.apiServer.extraArgs - extraVolumeMounts -> spec.apiServer.extraVolumeMounts - extraVolumes -> appended to spec.deployment.extraVolumes This unblocks OIDC SSO via the --oidc-* flags and, more importantly, structured authentication: --authentication-config mounted from a ConfigMap/Secret plus --requestheader-uid-headers, which is the only way to map a user UID for aggregated/extension apiservers. Because the control-plane Deployment runs on the management cluster, the passthrough is validated to preserve tenant<->management isolation: - extraVolumes allow only configMap and secret sources; host-reaching sources (hostPath, csi, nfs, persistentVolumeClaim) and token projection (projected) are rejected, so a tenant with self-service access to the Kubernetes CR cannot mount management-node paths or project arbitrary tokens into the apiserver pod. - each extraVolume must have a unique, non-empty name and exactly one source; the reserved names talos-ca and talos-tls-cert are rejected to avoid a duplicate volume name in the rendered podspec. - each extraVolumeMount must reference a user-declared extraVolume; the chart-managed talos secret volumes cannot be mounted. Regenerate values.schema.json, README, the Go types and deepcopy, and the ApplicationDefinition. Add helm unittest coverage for the default (no-op) render, each field's passthrough, the name/source guards, and the mount-reference guard (valid and rejected inputs).
