refactor: BasicInfoTab 拆分为 TypeScript 模块化组件

- 删除旧的 BasicInfoTab.js (~1000行)
- 新建 BasicInfoTab/ 目录，拆分为 10 个 TypeScript 文件:
  - index.tsx: 主组件（可配置 Tab）
  - config.ts: Tab 配置 + 黑金主题
  - utils.ts: 格式化工具函数
  - components/: 5 个面板组件 + LoadingState
- 主组件支持 enabledTabs、defaultTabIndex、onTabChange
- 应用黑金主题，支持懒加载 (isLazy)
- 更新 types.ts 添加 ActualControl、Concentration 等类型字段
