 * rc_ol_0016.pgc - 3-way 대사 조회 (승인·매입·입금) 온라인 서비스 (RC_OL_0016)
 *
 * 요청 KEY 의 원장 1건을 읽어 세 축을 교차 검증한다.
 *   leg1 : 승인(APPRAMT) == 매입(원장 amount)
 *   leg2 : 매입 - 수수료(fee) == 입금(DEPAMT)
 * 두 leg 모두 성립하면 3-way 정합(3WAY MATCH) 으로 보고, 상태가
 * 접수('R')/매입확정('M') 이면 정산완료('S') 로 전이한다. 어느 한
 * leg 이라도 깨지면 실패 leg(LEG1FAIL/LEG2FAIL) 를 식별해 실패('U').
 *
 * 입력 TXBUF:
 *   KEY     (필수) 처리키
 *   APPRAMT (필수) 승인금액
 *   DEPAMT  (필수) 입금금액
 * 출력 TXBUF:
 *   KEY / APPRAMT / CAPAMT / DEPAMT / LEG1 / LEG2 / RESULT / STATUS
 *
 * LEG1/LEG2 는 각각 "OK"/"NG" 로 응답하며, RESULT 는 3WAY MATCH
 * 또는 실패 leg 식별값(LEG1FAIL/LEG2FAIL) 이다.
