Reverse a soft delete and return the file to the workspace. Not a pure undo: the file comes back at the workspace root, and gains a _restored suffix when another file there already holds its name, so read folderPath and name off the response. Restoring an already-active file returns it unchanged, so a retry is safe. An archived workspace is a 400, and a name the restore could not free is a 409.
