fix(slideshow): filter out items missing logo images

Modified fetchItemIdsFromServer to include 'ImageTags' in the API request fields.
Added a filter to strictly exclude items that do not possess a Logo image.
This prevents the slideshow from displaying unstyled placeholders for media content lacking proper branding.
