Jira issue: CRDB-68049

Start with multitenant/tenantcostclient.TestConsumptionExternalStorage and the linked EngFlow invocation, focusing on the import_from_a_tenant_increments_ingress_bytes case and its captured logs. Reproduce the failure with the reported race, run, shard, and attempt parameters, then identify the cause and leave the test passing.
