feat: coaster-only toggle on live ride status panel

Queue-Times groups rides into lands (e.g. "Coasters", "Family", "Kids").
Capture that categorisation in LiveRide.isCoaster and surface it as a
toggle in the new LiveRidePanel client component.

- lib/scrapers/queuetimes.ts: add isCoaster: boolean to LiveRide,
  derived from land.name.toLowerCase().includes("coaster")
- components/LiveRidePanel.tsx: client component replacing the old
  inline LiveRideList; adds a "🎢 Coasters only" pill toggle that
  filters the grid; toggle only appears when the park has coaster-
  categorised rides; amber when active, muted when inactive
- app/park/[id]/page.tsx: swap LiveRideList for LiveRidePanel,
  remove now-dead LiveRideList/LiveRideRow functions
