 * lg_ol_0013.pgc - 원장 온라인 서비스 (LG_OL_0013)  [tier=hard]
 *
 * 원장 통계 조회: 요청 영업일(BIZDATE)의 원장을 상태코드별로 집계해
 * 접수(R)/처리완료(M)/불일치(U)/정산완료(S) 각 건수와 상태별 금액
 * 부분합, 전체 건수, 당일 금액 합계, 그리고 정산 진행률(정산건/전체)을
 * 한 번에 응답한다. 상태코드 배열을 순회하며 상태별 count/sum 을
 * 개별 집계 SELECT 로 산출한다.
 *
 * TxCore TX_SERVICE 엔트리. 요청 TXBUF 를 검증하고 lg_ledger 에
 * 직접 임베디드 SQL 을 반복 수행한 뒤 응답 TXBUF 를 구성한다.
