feat(admin): 用户体验体系化提升与高危缺陷修复

UX 缺陷修复:
- 校验失败不再卡死弹窗按钮(Users/Roles/Bills)
- 押金收取/批量收取/添加分期防重复提交;切换房型重置勾选
- AI 表单/批量确认不再出现"假成功"
- Dashboard 各数据模块独立加载,单接口失败不再整页清零
- 房间可视化加载失败显示错误态而非永久转圈
- 学生编辑表单回填前重置,避免字段残留污染
- 覆盖式导入增加二次确认;恢复默认考勤时段确认并同步表单
- 金数据匹配关闭前确认,同步中禁止误关

体验提升:
- 新增统一 QueryErrorState/QueryEmpty,20+ 页面加载失败显示错误态与重试
- 全局 ErrorBoundary + RouteKeeper 逐页兜底
- 新增 usePageVisible/useVisibleRefetch,保活页面切回自动刷新数据
- 新增首次登录角色引导 RoleTour 与业务闭环 NextStepHint 引导卡
- 重构 A2UI:useSubmissionState/useXCardSurface 收敛状态与命令生命周期,
  ArtifactErrorBoundary 渲染降级,图表空数据占位
- AI 助手欢迎语与建议话术按角色定制,会话列表空态引导
- 更新 a2ui-contract.md 契约文档说明实现现状
