feat(web): AI 文档查询卡片重构与单号判定统一

- documentClassification 抽出 isApplicationDocumentNo，统一兼容 AP-/APP- 旧格式与 A+8 新格式，aiDocumentQueryModel 复用
- aiDocumentQueryModel 文档卡片改为结构化字段布局（单据类型/金额/申请人/编号/操作），新增查询范围摘要区，渲染走 HTML 信任块
- AppShellRouteView/useAppShell/useRequests/detailAlerts/riskVisibility 等差旅详情模型适配单号判定
- 同步更新 ai-document-query-model/workbench-ai-mode-switch 测试，新增 document-classification 测试
