上传会员 KYC 文件到 Zinfra 私有存储

POST /v1/kyc/files scope: kyc:write
代会员调用 · 必带 x-on-behalf-of 需 x-idempotency-key

代会员调用。请求体直接放单个文件的原始字节；支持 JPEG、PNG、WebP与 PDF，单文件最大 8 MB。服务端不信任客户端声明的 Content-Type，会按文件魔数识别真实类型。

返回的 file_url 属于 x-on-behalf-of 指定会员的私有 KYC 目录。把它放进后续 POST /v1/kyc/applications 的profile.identity_photos.front/back/handheld。不要把外部 S3 URL 或 base64直接写进 KYC profile。

文件不可匿名访问，只能由该会员或具备 KYC 审核权限的 Zinfra 管理员读取。

字段类型必填说明
x-idempotency-key string 必填
x-on-behalf-of string 必填 会员的 external_member_id 或 mem_<uuid>。
