Fix P2P discovery port mismatch with HTTP API endpoints

- Change target ports from 9876/9877 to 8001/9877 (actual API ports)
- Fix region detection to use IP-based mapping instead of port-based
- Ensure P2P discovery connects to real HTTP API endpoints
- Resolve node isolation by testing correct service ports
