feat(web): 文档查询意图补充风险过滤与 X 天前范围

- aiDocumentQueryIntent 新增风险等级过滤（无/高/中/低/有风险）与 N 天前日期范围解析
- aiDocumentQueryModel/aiConversationHtmlRenderer 渲染适配风险过滤标签
- useWorkbenchAiDocumentQueryFlow/aiWorkbenchConversationStore 会话流转适配命令意图
- 更新 ai-document-query-model/ai-conversation-html-renderer/assistant-session-draft-delete 测试
