📄️ Call detail report
Lists the organization's calls ('Çağrı Detayları'), newest call first. Ordering is fixed at call_start_time DESC and cannot be changed: sending `sort` or `order` returns 422 rather than being ignored. When only one of date_from / date_to is given the other defaults to today; omitting both reports today. The date window may not exceed 365 days. Rows come from the reporting backend, so a temporarily unreachable backend returns 503. Requires `api_user|report_call_detail_view`.
