feat: 实现关注系统 + 通知侧边栏分类 TAB + 点赞聚合通知
- 新增关注系统：UserFollow 模型、FollowService（toggle/status/列表隐私控制） - User 新增 FollowersCount/FollowingCount/FollowListPublic/NotifyPrefs 字段 - Space 页面增加四态关注按钮（关注/已关注/回关/已互粉）+ 粉丝/关注数链接 - 新增 /space/:uid/followers 和 /space/:uid/following 列表页 - 新增 NotifyFollow/NotifyLikeAggregated 通知类型 - ReactionService 点赞时写入 daily_like_summary，访问时生成聚合通知 - FollowService 关注时触发 NotifyFollow 通知 - 消息中心侧边栏升级为分类 TAB（全部/系统通知/@艾特/点赞/关注） - NotificationService 新增 ListByCategory 按分类分页查询
