/**
 * The acquirer's own default processor — `processorName` on the account
 * (`default_processor_id` backend-side), which is what the Reconciliation Hub
 * pre-selects (GB-21646). `/merchants/{id}/processors` is the global processor
 * catalogue and carries no default, so it can't answer this.
 *
 * `isResolving` tracks only whether the account query is still in flight: the
 * query is gated on ACQUIRER:READ and a disabled react-query stays `idle`
 * (never `loading`), so a denied or failed read resolves to "no default"
 * instead of stalling the hub.
