feat: complete P2P polling app with vote management and UI improvements
- Add peer-to-peer polling with real-time synchronization via PeerJS - Implement vote changing, unvoting, and proper vote validation - Add modal interface for adding poll options - Fix vote inheritance issues for new users joining rooms - Create sidebar with available polls and connected peers - Add vote count synchronization across all connected peers - Implement proper vote state validation per user - Add localStorage persistence for polls and vote states - Create responsive design with modern UI components - Replace emojis with proper text-based icons - Add comprehensive error handling and user feedback - Support multiple polls with switching capabilities - Implement conflict resolution for concurrent voting
