Fetch a wallpaper image (public, unauthenticated)

GET 
/content/:id/wallpaper

Streams the wallpaper image bytes. This route carries NO authentication by design: the same URL is fetched by a kiosk WebView CSS background and by the native WallpaperManager, neither of which can present a credential. It serves only content whose metadata.is_wallpaper is true, so it cannot be used to enumerate other content by UUID. Access control is the unguessable UUID plus that flag.
