feat: unify operation feedback and improve failure recovery

 - DataGrid 使用原生 selection、排序、固定列、横向滚动、ActionBar、EmptyState 和 compound Pagination。
 - 流程业务列表默认每页 20 条，分页条使用宽度 128px 的 HeroUI Autocomplete 提供 20/50/100 条选择；通知中心仍固定每页 10 条。
 
+## 操作反馈浮层
+
+- 参考问题整改 `513706c` 的全局反馈及 `bfc5862` 的关闭按钮与保存成功反馈，接口成功、失败和降级警告统一由根部 `AppFeedback` 的 HeroUI `Toast.Provider` 展示；登录页、流程监控页、通知页和应用切换弹窗共用一个 Provider，页面不再渲染接口反馈横条。
+- 成功提示默认 4 秒、错误和警告默认 8 秒后自动消失。关闭按钮直接组合 HeroUI `Button`（`ghost`、`sm`、`isIconOnly`），通过官方 `slot="close"` 接入 Toast 关闭行为，使用 `AppIcons.Close`，位于内容右侧并随正文参与布局；前排图标始终可见，后排堆叠提示隐藏关闭按钮，Hover 和焦点样式沿用官方主题。关闭提示不清除请求失败状态、表单草稿或弹窗。
+- `src/design-system/feedback.css` 只约定 Toast 层级、顶部安全区与后排关闭按钮的可见性；层级 300 高于业务 Modal 和移动侧栏。不再放大带边框的默认关闭按钮，也不设置额外绝对位置或正文右侧占位；长文滚动和换行由 compound 内容组件承担，颜色、边框、圆角、阴影和 Hover 沿用 HeroUI 主题。
+- “编辑模板监控配置”和“定义显示字段”弹窗仅在 `updateRecord` 成功后关闭并显示保存成功 Toast；重新打开编辑、再次保存或离开页面时清理该来源提示，模板实例页切换模板或重新加载时也清理提示。保存失败保留弹窗和草稿。
+- 加载失败使用 HeroUI Pro EmptyState 和重新加载按钮；错误详情只出现在 Toast 中，提示关闭后仍可重试。同样的错误在每次重试失败时重新提示。
+
 ## 主题与资产
 
 - 当前固定浅色内容画布与深藏蓝侧栏直接使用 `xy-logo-red.png`，不加底色、不滤镜、不反色、不替换 RSM 标识。

 通知中的站内 URL 只剥离 `/oa_process_monitor_new/` 后交给 Umi history；其他应用或外部
 HTTP(S) 链接新窗口打开。`content` 始终作为纯文本渲染，不执行服务端 HTML。Navbar 首次加载
 及后续每 60 秒调用 `/notice/customer/count`，真实 0 条时不显示徽标，100 及以上显示 `99+`。
+
+## 10. 接口操作反馈与失败恢复
+
+入口覆盖登录与验证码、分组总览、模板实例列表、流程详情、通知中心和 Navbar 应用切换弹窗。
+
+- 新建分组、添加模板、编辑配置、取消监控、删除空分组、保存显示字段、附件下载及通知操作的成功或失败统一通过全局 HeroUI Toast 提示，不再在页面顶部追加常驻横条。Toast 位于业务弹窗和移动侧栏之上，页面滚动不影响其可见性。
+- 成功提示默认 4 秒后消失；错误和降级警告默认 8 秒后消失，悬停或键盘聚焦暂停计时。当前提示右侧的关闭图标始终可见，使用 HeroUI 默认小号透明按钮（`ghost` / `sm` / `isIconOnly`），点击或键盘激活通过 Toast 的 `close` slot 关闭；后排堆叠提示隐藏关闭按钮，避免误关闭。关闭与超时仅收起提示，不修改接口结果、失败状态、输入内容、选择项或弹窗状态；失败后可在原弹窗修正内容再次提交，相同错误也会重新提示。
+- 保存入口为分组总览的“编辑模板监控配置”和模板实例列表的“定义显示字段”弹窗。只有 `PUT /record/:name`（`updateRecord`）成功后才关闭弹窗，分别弹出“模板配置已保存。”或“显示字段配置已保存。”；显示字段同时更新当前列表列。模板配置在保存成功时立即反馈，随后重读列表；重读失败由加载错误和重试入口单独反馈。
+- 保存成功提示通过 `useFeedbackState('success')` 按来源管理；重新打开编辑、再次保存或离开页面时清理上一条提示，模板实例页切换模板或重新加载时也清理。正在保存时不重复提交；模板标题为空或缺少记录 ID 时不提交、不提示成功。保存失败只提示错误并保留弹窗及草稿。写入对象为 `audit_related_progress`，核心字段仍为 `title`、`metadata.department`、`metadata.template_code`、`metadata.conditions` 和 `metadata.fields_definition`；流程实例详情维持第 5.3 节的查看流程。
+- 分组总览、模板实例列表、流程详情和通知列表加载失败时保留 EmptyState 与重新加载入口，隐藏失败数据对应的列表或详情；关闭错误 Toast 后仍可重试，不把失败当作空数据。实例列表先读取模板与预设条件，再按当前关键字、页码、每页条数和条件查询实例；旧请求返回时不覆盖新请求结果。
+- 模板显示字段保存或附件下载失败只反馈本次操作错误，不把已加载列表切换为加载失败态；保存失败保留字段草稿。单个附件下载失败同样显示可关闭的错误提示。
+- 应用列表接口失败时通过警告 Toast 告知已回退当前账号的可访问应用；站点配置加载失败沿用原有默认配置回退并通过警告 Toast 提示。
+- 本次仅调整反馈呈现与重试交互，记录写入仍使用 `metadata`，对象仍为 `process_monitor_group`、`audit_related_progress`、`audit_progress_info`、`oa_member` 和 `oa_department`；Record API、通知接口、字段规则和权限保持现有协议。
