refactor: Community 目录结构重组 + 修复导入路径 + 添加 Mock 数据

## 目录重构
- DynamicNewsCard/ → DynamicNews/（含 layouts/, hooks/ 子目录）
- EventCard 原子组件 → EventCard/atoms/
- EventDetailModal 独立目录化
- HotEvents 独立目录化（含 CSS）
- SearchFilters 独立目录化（CompactSearchBox, TradingTimeFilter）

## 导入路径修复
- EventCard/*.js: 统一使用 @constants/, @utils/, @components/ 别名
- atoms/*.js: 修复移动后的相对路径问题
- DynamicNewsCard.js: 更新 contexts, store, constants 导入
- EventHeaderInfo.js, CompactMetaBar.js: 修复 EventFollowButton 导入

## Mock Handler 添加
- /api/events/:eventId/expectation-score - 事件超预期得分
- /api/index/:indexCode/realtime - 指数实时行情

## 警告修复
- CitationMark.js: overlayInnerStyle → styles (Antd 5.x)
- CitedContent.js: 移除不支持的 jsx 属性
