优化退款审核逻辑：驳回分恢复订单/关闭订单两种，优化状态标签，清理无用脚本

- AdminRejectRefund 新增 action 参数：restore 恢复订单至待交接，close 关闭订单并下架
- 前端驳回改为弹窗双选项：仅驳回恢复订单 / 驳回并关闭
- 清空 frontend placeholder 文件
- handleFileUpload 并发控制优化：清空上传列表时重置计数和 OCR 槽位
- v-for key 改为 _id 避免预览串图
- preview-src-list 改为单图预览
- deploy-prod.sh 新增 docker image/builder prune 自动清理垃圾
- scripts/ 删除无用的压测文件（load_stress.go 等 4 个）
