// Bank Reconciliation drilldown target). The menu-driven report-viewer navigation path
// (dynamicdrillDowntoReport -> Framework.ReportMenu.Get -> reportviewer.dbservice.ts) always
// POSTs a ReportCallingDTO{CriteriaDTO} envelope; the existing LoadBRS endpoint takes
// [FromBody] CriteriaDTO directly and would silently bind to a default/empty instance against
// that envelope shape -- same class of wire-shape mismatch as the Compliance dashboard wrappers.
