Override the stored tailscale targetPort in the start handler using the
actual port the start request landed on (req.socket.localPort), instead
of trusting a value the browser supplied. window.location.port can be
wrong behind a reverse proxy, ssh forward, or split deployment, and
silently funneling the wrong process is worse than the prior
"port-not-configured" error.
