feat(web): 票据夹资产缓存接入与 AI 工作台附件流程完善

- ReceiptFolderView 删除票据后提示已关联附件副本保留，接入 useToast；fetchReceiptFolderAsset 加 no-store 避免预览缓存
- PersonalWorkbenchAiMode 附件区/对话气泡适配资产缓存，personal-workbench-ai-mode.css 调整布局
- usePersonalWorkbenchAiMode/useWorkbenchAiApplicationPreviewFlow/useWorkbenchAiAttachmentAssociationFlow/useWorkbenchAiStewardFlow 完善附件草稿选择与关联流程
- travelRequestDetailSmartEntryRecognition 智能识别增强，AppShellRouteView/PersonalWorkbenchView/useApplicationPreviewEditor/useTravelReimbursementSubmitComposer 等配套适配
- 新增 expense-attachment-draft-selection、receipt-folder-asset-cache、travel-request-detail-smart-entry-recognition 测试，更新 attachment-association-confirmation、expense-application-fast-preview、workbench-ai-mode-switch 测试
