feat(home+search): KOSPI/KOSDAQ 인덱스 카드 + 검색결과 미니 sparkline

- Sparkline 컴포넌트를 PriceHero 내부에서 web/components/Sparkline.tsx 로 분리·재사용
- /api/markets/indices: macro_daily 의 kospi/kosdaq N일 시계열 + 최신값/전일대비
- 홈 IndicesPanel: 두 인덱스 카드(현재값/등락/우측 sparkline)
- /api/symbols/search?with_sparkline=true: 결과 한 번에 최근 30 종가 batch 조회
- SearchBox 결과 행에 mini sparkline + 현재가/등락률 인라인 표시
