修复设备模块导出报 TemplateRenderPolicy render error (500)：签名图片缺失时用透明图兜底

- UserUtils 新增 orTransparentPicture / getFinalUserSignatureOrTransparent（按id/按姓名），签名未配置或签名文件缺失时返回全透明图片，原方法保留不动
- cnas-device 13 个 ServiceImpl 共 31 处签名渲染调用换用兜底方法，覆盖校准计划、核查计划及明细/对比、保养计划、使用授权、利用外部仪器、事故报告、报废、故障维修、点检、量值溯源等全部 Word 导出
- DeviceStateServiceImpl（停用/启用导出）4 处"签名缺失塞 null"改为透明图兜底，移除旧人名查询与中断抛出
