Fix Bug #403: 住院医生工作站：应用医嘱组套后，药品明细字段内容丢失未正确引入表格

修复 handleSaveGroup 中 mergedDetail 和 newRow 构建时的空值处理问题：
1. mergedDetail 中 dose/doseQuantity/dispensePerDuration 使用严格 null 检查，
   避免组套中值为 null 时错误回退到 orderDetailInfos
2. newRow 中关键字段增加 mergedDetail 回退（?? 操作符），
   确保当 item 中字段为 null/undefined 时能从 setValue 填充的完整数据中获取
