Event cards link to /events/event-{id} instead of /events/{id}

## Bug Event cards on listing pages link to `/events/event-{id}` (e.g. `/events/event-123`) when they should link to `/events/{id}` (e.g. `/events/123`). The extra `event-` prefix doesn't match the real event detail route, so clicking a card sends the user to a broken/404 page. ## Expected Clicking an event card navigates to `/events/{id}` — the same URL shape used by the event detail route everywhere else in the app. ## Fix Remove the `event-` prefix from the card's `href` construction so it builds the URL as `/events/${id}` instead of `/events/event-${id}`. ## Found by Manual testing
