Subject: [PATCH 3/3] refactor: Move portfolio analytics to correct src/
 directory structure

- Move portfolio types to src/types/portfolio.ts
- Move portfolio calculations to src/utils/portfolioCalculations.ts
- Move portfolio hook to src/hooks/usePortfolioAnalytics.ts
- Move portfolio components to src/components/portfolio/
- Move portfolio page to src/app/portfolio/history/page.tsx
- Remove old root-level directories to match project structure
