FeatureItem.mediaType was never read anywhere -- the icon-vs-image choice is (correctly) driven by feat.image truthiness, set via the AssetPicker in FeaturesEditor. Neither the default items nor FeaturesEditor's "add item" object ever set it. Remove the dead field; image-precedence render/export behavior is unchanged.
