fix: pass relay-url and relay-token to auto-restart services

The server reads relay config from CLI flags, not config.json.
Auto-restart services (systemd on Linux, launchd on macOS, Registry
Run key on Windows) were launching the server without relay args,
so the tunnel never connected.

Now all three platforms pass --relay-url and --relay-token to the
server binary in their auto-restart configuration.
