Select FlavourStandalone explicitly.

Any value other than generator.FlavourHyperShift uses cloudConfigStandalone. Match generator.FlavourStandalone explicitly, and return an error for unsupported values. This prevents an unsupported cluster flavour from silently selecting the standalone ConfigMap.

As per coding guidelines, use FlavourStandalone for regular OpenShift clusters and FlavourHyperShift for hosted control plane clusters in ClusterFlavour configuration.

Update the cluster flavour selection around cloudConfigName to explicitly handle
generator.FlavourStandalone and generator.FlavourHyperShift, using
cloudConfigStandalone for the former and cloudConfigHyperShift for the latter;
return an error for any unsupported flavour instead of defaulting to standalone.

Align the HyperShift node volume and ConfigMap sync.

ExtraReplacementsFunc reads openstack-cloud-config, but createConfigMapSyncer and the generated HyperShift node manifest use cloud-provider-config. When openstack-cloud-config contains ca-bundle.pem, os-certAuthorityPath can point to a CA file that the node plugin does not mount. Use the same ConfigMap name and ca-bundle.pem key for the HyperShift node volume and sync path.

Read the cloud ConfigMap from its owning namespace.

On standalone clusters, cloudConfigName is cloud-provider-config in openshift-config, while c.ControlPlaneNamespace is the operator namespace. The lookup can miss ca-bundle.pem and leave ${MANILA_CA_CERT_PATH} empty. Use the openshift-config client and namespace for standalone clusters. Keep c.ControlPlaneKubeClient and c.ControlPlaneNamespace for HyperShift.

Propagate ConfigMap read errors instead of using an empty CA path.

When ConfigMaps(...).Get(...) returns an error, ExtraReplacementsFunc logs it and maps ${MANILA_CA_CERT_PATH} to "". GetAsset then writes an empty os-certAuthorityPath to the Manila CSI Secret. A cluster that requires a private CA may therefore use the system trust store and fail Manila API connections.

Keep an absent or empty ca-bundle.pem entry as the no-CA case. Return or retry other API errors through the asset-generation contract.
