Improve publishers page UI: fix agent counting, add pluralization, simplify version display

Replaces confusing agent version counting with clear distinction between unique agents and total versions. Removes interactive version badges in favor of simple "Latest: v{version}" text display. Adds proper pluralization to version badges and deletes unused VersionButton component.
