Walkthrough

The PR refactors scrolling behavior in the Q&A section component. A new helper function scrollToTop() replaces element-based scrolling, and pagination logic is simplified by removing mobile-dependent checks and using a pending scroll flag instead.

🐰 Scroll up, up, and away we go,
No mobile checks to slow the flow,
