Add upload of generator site for testing

So now we'll push the website build up to Space and serve it from the back-end. I'll just need to introduce the static files endpoint and download the archive there, then also add the deployment for the cloud console with the internal URL and testing parameters.

And for a follow-up to why the TC script builds were failing - nobody has any idea why but it magically stopped failing so I guess we're good now 🤡

I'm also thinking that it would be in our best in general if we start bundling our generator site with the back-end instead of using github pages. This way we can tweak our analytics, use better routing (instead of #), and provide some templating of pages to get better link preview metadata in the html head.
