feat(WEB): 절곡품 선생산→재고적재 Phase 1 - 생산입고 기반 구축

- StockTransaction: REASON_PRODUCTION_OUTPUT 상수 및 '생산입고' 라벨 추가
- StockLot: work_order_id FK 컬럼 마이그레이션 + 모델 fillable/casts/relation 추가
- StockService: increaseFromProduction() 메서드 구현 (increaseFromReceiving 기반)
- WorkOrderService: 완료 시 sales_order_id 유무에 따라 출하/재고입고 분기
  - stockInFromProduction(): 품목별 양품 재고 입고 처리
  - shouldStockIn(): items.options 기반 입고 대상 판단
