feat(stock-lab): 포트폴리오 매입가(purchase_price) 컬럼 분리 + 원달러 환율 부호 보정

Browse Source 
원달러 환율:
- 네이버 환율 change_value에 부호가 없어 프론트에서 항상 상승으로 인식되던 문제
- direction(red/blue) 기반으로 +/- 부호 prepend

포트폴리오:
- portfolio 테이블에 purchase_price 컬럼 추가 (기존 row는 avg_price로 백필)
- avg_price(평균단가): 손익률 계산 기준 (cost_basis)
- purchase_price(매입가): 총 매입 금액 요약 표시 기준
- API: PortfolioItemRequest/UpdateRequest에 purchase_price(Optional) 추가
- GET /api/portfolio 응답 holdings에 purchase_price 포함, summary.total_buy는 매입가 합계, total_profit_rate는 평균단가 기준
