feat: blue dot + Weather Delay notice for storm-closed parks

- Dot turns blue (instead of green) during weather delay on homepage
- Mobile card "Open today" badge becomes blue "⛈ Weather Delay"
- Park page LiveRidePanel shows a blue "⛈ Weather Delay — all rides currently closed" badge instead of "Not open yet — check back soon"
- Added --color-weather-* CSS variables (blue palette)
