Merge branch 'main' into fix/1414

Replaces hardcoded ws://143.198.27.163:8765 in HUD status display
with dynamic URL matching the actual WebSocket connection.

Before: ws://143.198.27.163:8765
After:  ${protocol}//${window.location.host}/api/world/ws

Fixes:
- HUD now shows correct URL through proxy/nginx
- No exposed internal IP
- Works with any deployment configuration

Fixes #1414

- * - Server responds with pong + user count
- * - Client auto-reconnects on missed 2 heartbeats
