fix: Make marquee text visible on hover by removing overflow clip

The marquee animation was working but the text was still clipped by
overflow:hidden on both the parent container and the text div itself.
Added group-hover:overflow-visible to both containers so the full
text becomes visible when the marquee animation starts on hover.
