polish: ride count copy, open indicator, and badge sizing

- "X rides open" → "X rides operating" (desktop + mobile)
- Green glowing dot next to park name when actively operating
- Hours text in calendar cells: larger (0.78rem) and bolder (600)
- Parks open badge: green tint when parks are open, larger text
