deploy(hub): bump manifests/hub.yaml image to v0.7.2 (host-domain ingest + storage_targets)

Live hub was v0.6.3 (pre host-report endpoint); v0.7.0-v0.7.2 were changelogged but
the manifest was never bumped. This deploys the host-domain ingest (slice 3) +
storage_targets (slice 5 Phase A). Additive/idempotent migrate(); controller path untouched.
