 * rc_bt_0005.pgc - 승인-매입 금액불일치 검출 배치 (RC_BT_0005)
 *
 * 지정 영업일의 접수('R') 건을 커서로 순회하며 수수료 정합성을 검증한다.
 * 업무규칙: 표준 수수료율 2.5% 로 역산한 추정수수료
 *          exp_fee = amount * 25 / 1000 과 실제 수수료(fee) 의 절대차가
 *          허용오차 RC_TOL_ABS(원) 를 초과하면 금액불일치 → 불일치('U'),
 *          허용범위 이내면 매입확정('M') 으로 전이한다.
 *          불일치 차액을 누계하여 리포트한다.
 *
 * 실행:  rc_bt_0005 <YYYYMMDD> [db@host]
