refactor(Company): fetch 请求迁移至 axios

- DeepAnalysis: 4 个 fetch → axios
- DynamicTracking: 3 个 fetch → axios (NewsPanel, ForecastPanel)
- MarketDataView/services: 4 个 fetch → axios
- CompanyOverview/hooks: 9 个 fetch → axios (6 个文件)
- StockQuoteCard/hooks: 1 个 fetch → axios
- ValueChainNodeCard: 1 个 fetch → axios

清理:
- 删除未使用的 useCompanyOverviewData.ts
- 移除所有 getApiBase/API_BASE_URL 引用

总计: 22 个 fetch 调用迁移, 复用项目已有的 axios 拦截器配置
