 * rc_ol_0025.pgc - 수수료 대사 온라인 서비스 (RC_OL_0025)
 *
 * 요청 KEY 의 원장 1건을 읽어 수수료를 대사한다. 입력 수수료율(RATEBP)
 * 은 basis point 단위(250 = 2.5%)로, 기대수수료는
 *   EXPFEE = amount * RATEBP / 10000
 * 로 계산한다. 실제수수료(fee) 와의 차이(FEEDIFF = fee - EXPFEE) 절대값이
 * 1원 이하이면 일치로 보아 매입확정('M')/MATCH 로, 아니면 불일치('U')/
 * FEEMISMATCH 로 상태를 전이한다. (커서 미사용)
