fix: 견적 V2 자동 견적 산출 UI 오류 수정

- actions.ts: BomBulkResponse 타입, FinishedGoods에 has_bom/bom 필드 추가
- QuoteRegistrationV2.tsx: handleCalculate 응답 처리, DevFill BOM 필터링
- LocationDetailPanel.tsx: bomItemsByTab process_group 기반 매핑
- QuoteSummaryPanel.tsx: detailTotals grouped_items 기반 계산

해결된 문제:
1. 오른쪽 패널 제품 리스트 미표시
2. 개소별 합계(상세소계) 미표시
3. 상세별 합계(그룹) 미표시
4. 예상 견적금액 0원 표시
