Answer 1

File input should be empty when edit your entity and this is the default behavior. to make it required false in edit you can use add this simple solution.
'required'=> is_null($builder->getData()->getId())
if you upload a new image, it should replace the old one, otherwise do nothing.
if you want to show the image, you can do it directly in the twig with <img> tag
