fix(service): stop waiting on a service that no longer starts with Windows

When the service's start type was changed from automatic, startup waited
about two minutes for it before falling back to Sidecar. Detect this
immediately, skip the TUN readiness wait, and offer a reinstall that
restores automatic start.
