Upgrade Kotlin to 2.3.0, refine MainView, and update dependencies

Updated Kotlin Multiplatform to 2.3.0 for enhanced compatibility and improvements. Streamlined `MainView` with cleaner structure, added responsive scaling, and introduced a `HiddenCss` class. Upgraded various dependencies, including `vst-ui-base` to 2.2.3 and `midi-arrays` to 0.3.6, ensuring better functionality and consistency. Added changes to build task configurations for improved build pipelines.
