- TravelRequestApprovalDialog 增强审批交互，TableLoadingState 补充表格加载占位，ConfirmDialog 扩展确认对话框能力
- useAppShell/useRequests/AppShellRouteView 配套适配申请详情跳转与会话状态
- 同步更新 requestProgressSteps、travel-request-detail-leader-approval、assistant-session-draft-delete、documents-center-status-filter、app-shell-financial-assistant-entry、request-progress-viewer 等测试
