Description

In the web UI, clicking the prompt composer + button while connected to a remote/non-local server opens the in-app project file picker instead of the browser/device attachment picker.

This makes it difficult or impossible to attach local device files, especially on mobile where the expected behavior is to attach a screenshot, photo, PDF, or text file from the phone.

The behavior appears to come from the prompt attach action switching on server locality:

if (server.isLocal()) {
  fileInputRef?.click()
  return
}

dialog.show(() => <DialogSelectFile mode="files" ... />)

That flow was originally introduced for WSL/server files, but after the condition changed to server.isLocal(), it applies to all remote servers.
