fix: correct hero abacus scroll direction to flow with page content

The hero abacus was scrolling in the opposite direction of page content due to incorrect math. Fixed by subtracting scroll position instead of adding it.

Change: top: calc(50vh - ${scrollY}px) instead of calc(50vh + ${scrollY}px)

Now the abacus properly scrolls up with the page content when scrolling down.
