feat(web): AI 工作台会话与文档卡片渲染增强

- aiConversationHtmlRenderer 识别单据记录类表格并渲染为卡片列表，新增删除申请单详情的禁用占位链接
- aiWorkbenchConversationStore 增加草稿删除后会话链接失效处理，避免点击已删除单据跳转
- aiApplicationPreviewActions 调整提交/草稿调用路径，PersonalWorkbenchAiMode 接入新的会话存储与渲染
- ConfirmDialog/TravelRequestDeleteDialog/useAppShell/AppShellRouteView 配套适配，同步更新相关前端测试
