feat: park page operating window check; always show ride total

- Extract isWithinOperatingWindow() to lib/env.ts (shared)
- Park detail page: always fetch Queue-Times, but force all rides
  closed when outside the ±1h operating window
- LiveRidePanel: always show closed ride count badge (not just when
  some rides are also open); label reads "X rides total" when none
  are open vs "X closed / down" when some are
