feat: show live open ride count in park name cell

- Fetch Queue-Times ride counts for parks open today (5min cache)
- Only shown within 1h before open to 1h after scheduled close
- Count displayed on the right of the park name/location cell (desktop)
  and below the open badge (mobile)
- Whole park cell is now a clickable link
- Hover warms the park cell background; no row-wide highlight
