DefaultNSResolver().Snapshot() returns only namespaces registered via
AddNamespace(). Storagesvc does not listen to namespace events, so tenant
namespaces (fission-*) are never registered and their Package CRDs are
invisible to the pruner — causing all archives to be treated as orphans
and deleted.
Fix: use metav1.NamespaceAll to list Packages across all namespaces.
Remove unused pkg/utils import.
