    // The [FromBody] property must be literally named/typed ReportCallingDTO, not a custom wrapper —
    // BaseEndpoint.GetReportCallingDTOFromRequest finds it via reflection on that exact property name
    // whenever the client sends an "H-ReportFormat"/"ReportFormat" header (which the frontend does
    // unconditionally for any MenuType=="Reports" menu, which this is). A custom wrapper class here
    // makes that lookup return null and 400s with "Report export requires a ReportCallingDTO..." even
    // though this endpoint never runs the export path itself. ReportCallingDTO.CriteriaDTO already
    // matches the { "CriteriaDTO": { "SectionCriteriaList": [...] } } body reportviewer.dbservice.ts's
    // existing generic GB5 branch sends — so this satisfies BaseEndpoint's check with no FE change.
