yuetsh d7d80e1c1b feat(achievement): 添加全局解锁弹窗与待弹拉取
推拉结合:布局层每次路由切换拉一次 pending 作为主通道,
WebSocket 只作为在线时的即时增强。纯靠推会丢消息——
前端 WebSocket 只在问题页且有提交监听时才建连。

/**
* 成就解锁弹窗队列。
*
* 通知走推拉结合,后端的 UserAchievement.notified 是唯一真相来源:
* - 拉(主):布局层每次路由切换拉一次 pending覆盖全部场景绝不丢
* - 推增强WebSocket 只在用户当场停留在问题页时把延迟压到几百毫秒
*
* 之所以不能只靠推:前端 WebSocket 不是常驻连接,只在问题页且有提交监听时
* 才建连,纯推会丢消息(尤其是题单奖章,那些页面根本没建连接)。
