feat: 空状态引导全面应用与考勤批量标记

admin:
- 17 个列表页空态统一为 QueryEmpty 引导:学生/账单/入住/费用/押金/
  教室/房间/班级/考试/排课/机构/考勤机/钱包/租赁/通知/角色等,
  有创建权限的页面附带主操作按钮,无权限时纯展示
- 教师端课堂点名新增「全部已打卡/全部未打卡」批量按钮:
  仅作用于状态不一致的记录,确认后调用批量接口,展示成功/失败数量

server:
- 新增 PUT /attendance-records/batch-status 批量改状态接口
  (ids ≤200,逐条权限校验与会话锁,部分失败返回 failedIds,
  审计日志记录批量结果;路由声明在 :id 之前避免被捕获)
