handle /ws_debug/health in debugger and add request logging (#8426)

- Fix debugger HTTP health endpoint to also match /ws_debug/health
  (ingress forwards the full path, not just /health)
- Add request logging to all three extra services (LSP, multiplayer,
  debugger) for HTTP and WebSocket ping/upgrade events
