feat: Phase 3 단가 테이블 마이그레이션 추가

- Phase 3.1: price_motor → items (SM) 누락 품목 13건 추가
  - PM-020~PM-032: 제어기 (6P~100회선)
  - PM-033~PM-035: 방화/방범 콘트롤박스, 스위치
- Phase 3.2: price_raw_materials → items (RM) 누락 품목 4건 추가
  - RM-007~RM-011: 신설비상문, 제연커튼, 화이바/와이어원단
- 중복 확인 로직: 기존 품목명과 mb_strtolower 비교
- 최종 결과: items 651건, prices 651건, BOM 18건
