Enhance Wi-Fi Aware robustness and debug UI display

- Clean up transport resources (sockets, server sockets, network callbacks) immediately on peer disconnection.
- Implement resolveScopedAddress to show scoped IPv6 (e.g., %aware0) in Debug UI.
- Fix Map type mismatch warning in ChatViewModel bridge.
- Filter self-ID from peer cleanup tables to prevent recursive self-removal.
