feat: 收藏夹系统 + Studio 趋势图 + 通知偏好设置
- 新增收藏夹系统 (Folder/FolderItem 模型、CRUD API、前端管理页) - 新增文章详情页收藏按钮 (书签图标、ToggleFavorite 一键收藏) - 新增 Studio 趋势图 (赋能值/评论/点赞/收藏 4 线图, 7d/30d/90d) - 新增通知偏好设置页 (评论/回复/点赞/关注 4 类开关) - 后端通知列表支持按偏好过滤 (排除已关闭的通知类型) - 下载 Chart.js 到本地静态资源 (static/js/chart.umd.min.js) - 补充收藏夹卡片、开关滑块、趋势图网格等 CSS 样式
