fix: add node get permission for DaemonSet mount affinity checking

The CSI node service account needs 'get' permission on nodes to check
if a DaemonSet can schedule on a specific node based on nodeAffinity.
Without this permission, the DaemonSet mount falls back to shared-pod
mode even when the node matches the affinity rules.
