feat(workspace): xlsx在线查看/编辑接入(2026-09-18用户要求)

- office_read.dspy: 按扩展名分流——xlsx/xlsm调univer-office的xlsx-to-workbookdata
  返回workbookData;docx原链路不变(顺带f-string改拼接合规)
- office_save.dspy: workbookData/documentData双字段分流,xlsx调workbook-data-to-xlsx回写
- workspace_view/open.dspy: office_exts扩为['.docx','.xlsx','.xlsm'],
  xlsx与docx同享在线查看(mode=view只读)+在线编辑+下载按钮
- 配套: univer-office仓11d83bc(IWorkbookData双向转换器+sheets插件+44断言往返自测)
