💡 What: Added busy state and disabled styling (opacity-50, pointer-events-none) to the IconButton component. Added a loading spinner indicator when busy is true.
🎯 Why: To ensure users receive clear visual feedback when icon-only actions (such as copying or refreshing) are processing or disabled, preventing confusion and multiple clicks.
📸 Before/After: IconButton previously had no disabled state, keeping pointer events active and without opacity changes, leading to poor UX. It now supports proper disabled and busy states.
♿ Accessibility: Prevents disabled elements from receiving focus, ensuring smoother keyboard navigation.
