 * lg_ol_0005.pgc - 원장 온라인 서비스 (LG_OL_0005)  [tier=medium]
 *
 * 원장 대사(對査) 잔액검증: 요청 영업일(BIZDATE)의 원장 합계(Σamount)
 * 를 집계하고, 요청자가 제시한 기대값(EXPECT)과 대조한다. 두 값이
 * 일치하면 정상(RESP_OK), 불일치하면 차액과 함께 RESP_INVALID 를
 * 반환한다. 불일치 진단을 돕기 위해 처리완료(M)/정산완료(S) 상태별
 * 부분합도 함께 산출한다. 조회 전용 서비스로 원장을 변경하지 않는다.
 *
 * TxCore TX_SERVICE 엔트리. 요청 TXBUF 를 검증하고 lg_ledger 에
 * 직접 임베디드 SQL(SUM/COUNT) 을 수행한 뒤 응답 TXBUF 를 구성한다.
