Our Info panel, hole punch race fix, NAT profiles in relay introduction

Browse source 
- Network Diagnostics: "Our Info" button shows addresses with NAT status,
  device role, UPnP, HTTP capability. Addresses stacked for mobile.
- Hole punch race: re-check for existing connection before and after relay
  introduction to avoid wasting minutes on redundant punch attempts.
- Relay introduction now carries requester/target NAT mapping+filtering
  so hole punch strategy uses fresh profiles instead of stale stored ones.
  Critical for phones that switch between WiFi/cellular/VPN.
- STUN fix: filter DNS results to IPv4 (was resolving to IPv6 first on
  dual-stack, causing silent send failure and "NAT unknown").
- Welcome screen: Ready button with loading bar for instant feed access.
- LAN addresses show just "LAN" (no misleading punchability label).
