fix(storage-users): add --orphaned upload session filter

Upload sessions whose node metadata can no longer be read can never
finish postprocessing, stay in processing state indefinitely and keep
consuming the quota of their space.

Wire up the Orphaned session filter so operators can list the affected
sessions and remove them with --clean:

    opencloud storage-users uploads sessions --orphaned
    opencloud storage-users uploads sessions --orphaned --clean
