chore(sms): retire the stuck macOS namespace

The macOS workload is scaled to 0 and its PVC macos-disk has been Pending
for 72 days against storage class longhorn-imessage-local. No node carries
the workload=imessage label it pins to. The namespace only holds that dead
PVC plus two unused Services. Remove the Application, the manifests and the
namespace so ArgoCD prunes them.

-# not have those labels.
