perf(MarketDataView): 优化数据映射性能和请求管理

- useMarketData: 使用 Map 替代 findIndex，O(n*m) → O(n+m) 性能优化 - useMarketData: 修复 React StrictMode 下请求被意外取消的问题 - config.ts: 添加 CompanyOverview 和 DynamicTracking 的骨架屏 fallback 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
