refactor: 하드코딩된 validation을 common_codes 기반으로 변경

- item_type_code: 기존 PRODUCT,MATERIAL 고정값 → common_codes 조회
- margin_rate: max:100 제한 제거 (100% 초과 마진 허용)
- client_type: 매입/매출/매입매출 common_codes로 이동
- bad_debt_progress: 협의중/소송중/회수완료/대손처리 common_codes로 이동
- product_category: 스크린/스틸 common_codes로 이동
- 마이그레이션 추가: client_type, bad_debt_progress, product_category 코드 그룹

수정 파일:
- PriceStoreRequest, PriceUpdateRequest
- ClientStoreRequest, ClientUpdateRequest
- QuoteStoreRequest, QuoteUpdateRequest
