 * cl_bt_0009.pgc - 마감 스냅샷 배치 (요약행 생성)  [tier=hard]
 *
 * 지정 영업일의 정산완료('S') 건을 집계(count/Σamount/Σfee)한 뒤,
 * 스냅샷 요약행을 cl_ledger 에 INSERT 한다.
 *   key      = <biz_date> + "SS"   (예: 20260717 -> 20260717SS)
 *   merch_id = "*SNAP"
 *   status   = 'S'
 *   amount   = Σamount,   fee = 마감건수(count)
 * 동일 스냅샷 키가 이미 있으면 재생성을 위해 선삭제한다.
 * 배치 main 엔트리 포함.
 *
 * 실행:  cl_bt_0009 <YYYYMMDD> [db@host]
