 * rc_ol_0028.pgc - 대사 균형검증 (CURSOR) 온라인 서비스 (RC_OL_0028)
 *
 * 요청 영업일(BIZDATE)의 원장을 커서로 순회하며 승인 잔여금액과
 * 매입/정산금액을 각각 누적하여 두 축의 균형(밸런스) 여부를 검증한다.
 *
 * 업무규칙:
 *   - 접수('R')            → 승인 잔여   SUMAPPR 에 amount 누적
 *   - 매입확정('M')/정산('S') → 매입/정산 SUMCAP  에 amount 누적
 *   - 차이 GAP = SUMAPPR - SUMCAP
 *   - GAP 이 0 이면 BALANCED=Y, 아니면 BALANCED=N
 *
 * 응답: BIZDATE, SUMAPPR, SUMCAP, GAP, BALANCED  (읽기 전용)
