 * rc_bt_0016.pgc - 대사 diff 리포트 배치 (RC_BT_0016)
 *
 * 지정 영업일의 원장을 가맹점번호(merch_id) 순으로 커서 순회하며 가맹점별
 * 승인측/매입측 금액 차이를 리포트한다. (읽기 전용 - 상태변경 없음)
 * 업무규칙: 승인측 = status='R' 금액 합계, 매입측 = status in('M','S') 금액 합계.
 *          가맹점이 바뀔 때 차액(승인측-매입측) 라인을 출력하고, 차액이 0 이
 *          아닌 가맹점을 불일치 가맹점으로 계수한다.
 *
 * 실행:  rc_bt_0016 <YYYYMMDD> [db@host]
