[bugfix] Fix Load Image (from Outputs) node failing on macOS

Filter out .DS_Store and placeholder files from remote widget file lists.

On macOS, the .DS_Store file (a hidden system file created by Finder) was
being included in the output folder file list. When the "Load Image (from
Outputs)" node refreshed, it would select .DS_Store as the first file,
causing the image preview to fail with an error since .DS_Store is not a
valid image file.

This fix filters out .DS_Store and the _output_images_will_be_put_here
placeholder file from file lists returned by remote widget API calls.
