Summary

Ports the Artwork Selector feature from the Moonfin-Core client over to the Smart-TV client. This enables administrative users to search, view, download, and delete custom artwork (Posters, Backdrops, Logos, Banners, etc.) directly on the TV interface with full Enact/Sandstone D-pad focus control.
