feat: [QMS] 2일차 로트 추적 심사 API 구현 (Phase 1)

- QmsLotAuditService: 품질관리서 목록/상세, 8종 서류 조합, 서류 상세(2단계 로딩), 확인 토글
- QmsLotAuditController: 5개 엔드포인트 (index, show, routeDocuments, documentDetail, confirm)
- FormRequest 3개: Index, Confirm, DocumentDetail 파라미터 검증
- QualityDocumentLocation: options JSON 컬럼 추가 (마이그레이션 + 모델 casts)
- IQC 추적: WorkOrderMaterialInput → StockLot → lot_no → Inspection(IQC) 경로
- 비관적 업데이트: DB::transaction + lockForUpdate() 원자성 보장
