Remove unreachable image_box drag-and-drop UI

image_interface and meta_data (admin_interface.js), the sort_images
action and route, and their admin.css rules -- the old vertical
image_browser sidebar this all depended on isn't rendered by any
current view. related_assets.js and the star-toggle sidebar fully
supersede what this did.

Confirmed unreachable via full grep across app/, config/routes.rb,
and admin_bundle.js before removal -- route, controller action, and
JS handler were all individually real and functional, just with
nothing left anywhere that could ever trigger them.
