Responsive UI for MainMenu & LoadingScreen

Convert MainMenu and LoadingScreen UXML/USS to responsive layouts (percent-based sizing, media queries for wide/tall screens), adjust spacing, fonts and colors, and refine spaceship icon and button styles. Update MainMenu and LoadingScreen controllers to force the root TemplateContainer to occupy the full screen. Add Assets/Resources.meta. Update metadata and LFS object IDs for several Unity assets (ReflectionProbe-0.exr.meta importer fields and AssetOrigin, Komikax font LFS oid, Loading.unity, DefaultVolumeProfile.asset, and project settings hashes) to reflect import/serialization changes.
