feat(common-codes): order_status/order_type 공용 코드 추가

- common_codes 테이블에 order_status 코드 그룹 추가 (DRAFT, CONFIRMED, IN_PROGRESS, COMPLETED, CANCELLED)
- common_codes 테이블에 order_type 코드 그룹 추가 (ORDER, PURCHASE)
- CommonController index 메서드 구현 (GET /api/v1/settings/common/{group})
- 멀티테넌트 지원 (tenant_id NULL 또는 현재 테넌트)
