refactor(DeepAnalysisTab): 模块化拆分为 21 个 TypeScript 文件

将 1,796 行单文件拆分为原子设计模式结构：

**atoms/** - 原子组件
- DisclaimerBox: 免责声明警告框
- ScoreBar: 评分进度条
- BusinessTreeItem: 业务树形项
- KeyFactorCard: 关键因素卡片

**components/** - Card 容器组件
- CorePositioningCard: 核心定位
- CompetitiveAnalysisCard: 竞争地位分析（含雷达图）
- BusinessStructureCard: 业务结构
- ValueChainCard: 产业链分析
- KeyFactorsCard: 关键因素
- TimelineCard: 发展时间线
- BusinessSegmentsCard: 业务板块详情
- StrategyAnalysisCard: 战略分析

**organisms/** - 复杂组件
- ValueChainNodeCard: 产业链节点（含 RelatedCompaniesModal）
- TimelineComponent: 时间线（含 EventDetailModal）

**utils/**
- chartOptions.ts: ECharts 图表配置

优化效果：主文件从 1,796 行减少到 117 行（-93%）
