fix(mouse_area): update hover state on scroll events

Browse source 
Hover state was only recalculated on CursorMoved events, causing items
to remain highlighted after scrolling away from them. Now hover checks
also run on WheelScrolled events and viewport changes, ensuring
on_enter/on_exit fire correctly when content moves under the cursor.
