feat(items+einvoices): 품목 상태값 제거 + 공급업체/거래처 조회조건 + 합계 면세/과세 분리

- 품목관리(items):
  · STATUS 컬럼 표시/필터/폼에서 제거 (전부 ACTIVE 가 default — 사용자 사용 안 함)
  · 조회조건에 공급업체 SearchableSelect 추가 (이미 백엔드 vendorObjid 지원)
- 계산서 발행(einvoices):
  · 조회조건에 거래처 SearchableSelect 추가 (customers list API 사용)
  · 페이지 하단 tfoot 에 면세 합계 / 과세 합계 / 총 합계 분리 표시
