Ssr

Port this https://github.com/inertiajs/inertia-laravel/blob/2.x/src/Ssr/HttpGateway.php, should be pretty straight forward.

The vite part might be a bit trickier though, will have to look into that. [docs](https://inertiajs.com/server-side-rendering#setup-vite-js)

Maybe there is a way to make the ssr implementation more "tempesty"?
