backup-node: torn-backup floor guards the main data volume only

Browse Source 
A 0G sidecar volume (ronin eigenda-proxy) FATAL'd the whole backup before the
manifest was written - verify found no new backup and the refresh pipeline's
bench-retire escalated 4 cycles in a row, head-of-line blocking the single
refresh lane. Sidecars are legitimately tiny; the <1G fail-closed floor now
applies only to the main data volume (key == compose basename).
