Add real-time sync, c3nav integration, and PWA icons

Features:
- Automerge-based real-time room sync with CRDT
- c3nav indoor map integration for CCC events
- DualMapView component (auto-switches indoor/outdoor)
- useRoom hook for room state management
- PWA icons and manifest

Infrastructure:
- DNS configured for rmaps.online, www, and *.rmaps.online
- Cloudflare tunnel updated for wildcard subdomains
- Fixed Next.js security update to 14.2.28
