// AppsFileList lists files in a Miaoda app's storage (cursor pagination)。
//
// GET /apps/{app_id}/storage/file_list。过滤器：--name / --path / --type / --size-gt /
// --size-lt / --uploaded-since / --uploaded-until（精确或区间），分页 --page-size/--page-token。
// file 域不分 dev/online，无 --env。
//
// pretty 渲染 5 列：file_name / path / size / type / uploaded_at；空结果打 "No files found."。
// server 字段 created_at → 产品语义 uploaded_at。
