feat: 实现 Redux 全局状态管理事件关注功能

Browse Source 
本次提交实现了滚动列表和事件详情的关注按钮状态同步：

✅ Redux 状态管理
- communityDataSlice.js: 添加 eventFollowStatus state
- 新增 toggleEventFollow AsyncThunk（复用 EventList.js 逻辑）
- 新增 setEventFollowStatus reducer 和 selectEventFollowStatus selector

✅ 组件集成
- DynamicNewsCard.js: 从 Redux 读取关注状态并传递给子组件
- EventScrollList.js: 接收并传递关注状态给事件卡片
- DynamicNewsDetailPanel.js: 移除本地 state，使用 Redux 状态

✅ Mock API 支持
- event.js: 添加 POST /api/events/:eventId/follow 处理器
- 返回 { is_following, follower_count } 模拟数据

✅ Bug 修复
- EventDetail/index.js: 添加 useRef 导入
- concept.js: 导出 generatePopularConcepts 函数
- event.js: 添加 /api/events/:eventId/concepts 处理器

功能：
- 点击滚动列表的关注按钮，详情面板的关注状态自动同步
- 点击详情面板的关注按钮，滚动列表的关注状态自动同步
- 关注人数实时更新
- 状态在整个应用中保持一致
