Roadmap list view: screen readers announce bare vote/comment counts

UX audit finding

On /roadmap?view=list, each row's accessible name concatenates title + vote count + comment count + prioritize count without labels, e.g. "Search upgrade… 0 0 0". Confusing for assistive tech and looks broken in accessibility tree.

Fix: Add aria-label on metric spans (47 upvotes, 2 comments) and hide decorative icons from the name.
