fix: code-review 审查问题修复 + A2UI 测试补齐

Standards 轴:
- 移除 uiArtifacts.ts 的 payloadOf 死代码残留
- AttendanceDevices 残留 any 类型化(补 ClassroomOption.status 字段)
- 批量考勤纠错区分业务失败(已结算/无权限)与系统错误,
  前端提示精确到两类数量
- Dashboard queryFn 六段重复校验块收敛为 safeValidate 助手

Spec 轴:
- 补齐阶段 3.4 A2UI 测试:图表空数据占位、ArtifactErrorBoundary
  降级隔离、useSubmissionState/useXCardSurface 单测(7 用例)
- 阶段 2.2 补两处引导:教师工作台区分「今日无课」与「未分配班级」、
  班级花名册空态带「添加学员」动作
- 契约文档修正 DynamicReview 状态管理描述(多提交点如实说明)

aislop 剩余 16 警告均为必要豁免(类型边界/声明式 SQL 配置/既有文件规模)
