For now, the SSR mode only works partially.

We're able to render a component from SSR and resume it, but we're not able to interact with it as the qwik loader is trying to actually fetch the QRLs and we don't have any server running.

If we want to pursue this effort (to render components in SSR mode), we'll have to find a creative way to simulate being in the browser without actually having to fetch the QRLs from a server.

Any feedback/suggestion is welcome.
