test(app-shell): two ResourceEditPage zh cases await the lazy studio zh catalogue

`discardDraftLabel-12690` finds the `丢弃草稿` button
(`engine.edit.discardDraft`) and `environmentOverlay-12141` reads the
read-only banner (`engine.edit.readOnlyTypeBanner`) in zh-CN. Both rows
moved into the lazy `studio` namespace with the editor strings, so each
case raced the zh chunk. Load the catalogue at module scope.
