refactor: 抽取通用 Tab 容器组件，重构 BasicInfoTab 和 DeepAnalysisTab

新增组件：
- TabPanelContainer: 三级容器，统一 loading 状态 + VStack 布局 + 免责声明
- SubTabContainer: 二级导航容器，支持黑金/默认主题预设

重构：
- BasicInfoTab: 使用 SubTabContainer 替代原有 Tabs 实现
- DeepAnalysisTab: 拆分为 4 个子 Tab（战略分析/业务结构/产业链/发展历程）
- TabContainer: 样式调整，与 SubTabContainer 保持一致
