feat(Blenvy): basic working loading of levels & assets

* removed/ obsoleted blueprintsList
 * now using AllAssets (meh naming)
 * modified example & internals to enable loading levels as Blueprints as well
 * internals quite messy for now, needs a big cleanup still
 * disabled materials library for now, needs to be overhauled to make use of asset logic as well
 * added more mock assets for testing
 * related changes to blender & bevy side
