feat(auto_export): continued cleaning up overhaul

* added both gltf exporter button AND auto export button to side bar
 * added storage of gltf settings
 * auto_export now uses stored gltf settings
 * updated override strategies of defaults vs gltf settings
 * removed all gltf specific (not auto export) parameters from preferences
 * updated auto export operator params changed logic to use updated system
 * updated bevy integration test
 * ui improvements
 * various tweaks
