fix: 정산 배치 파이프라인 정합 — 매퍼 NULL 파라미터 + override_settle 제약 + 정산지급 데이터

정산/지급 화면이 전부 비어있던 원인: 운영 DB에서 정산 배치가 실행된 적 없음.
MONTHLY_SETTLEMENT 배치를 돌리는 과정에서 발견한 버그 수정 + 데이터 구성.

매퍼 버그 (PG: could not determine data type of parameter):
- RegulatoryLimitMapper/ChargebackGradeMapper/InstallmentRatioMapper:
  #{productCategory} 가 IS NULL 비교에 쓰여 타입 추론 실패 -> jdbcType=VARCHAR 명시
- ForecastKpiMonthlyMapper: #{targetOrgId} 동일 -> jdbcType=BIGINT 명시

스키마 (V79):
- override_settle.settle_id NOT NULL 완화 — calcOverride(Step7)는 settle_master
  생성(Step8) 전 단계라 settle_id 를 채울 수 없음

데이터 (V80):
- 배치 실행 결과: settle_master 150 / 원장 433 / 명세서 112 / 분개 433 (2026-02~04)
- payment 는 settle_master 파생 생성, 운영성 도메인(공제/마감/세금계산서/이의신청/
  시책/정정)은 대표 샘플 시드 (멱등 NOT EXISTS)

검증: 배치 12스텝 COMPLETED, 정산/지급 10개 엔드포인트 200 OK.
