perf(media): 生产媒体直传阿里云 OSS

Browse Source 
生产同构验收确认 server_main_openapi 上传通道在媒体高并发下产生 381 个 502，并将已创建任务的 p95 拉高到 172 秒。\n\n为 request_asset 与 image_result 增加环境配置控制的阿里云 OSS 直传，保留普通上传原通道；使用 Kubernetes Secret 注入凭据，并对签名、重试、场景隔离和生产配置校验增加测试。\n\n验证：Go 全量测试、go vet、OpenAPI、迁移安全检查、Kustomize/Compose 渲染、gofmt 与 git diff --check 均通过；真实 OSS PUT/CDN 读取探针通过且对象已清理。
