UI

Now builds with support for the new UI

[bernhardberger]

Thanks for putting this together. I found it while looking into why /gui is disabled in the current image. This looks like the right change.

I checked the repo's contribution guide and noticed a few things that are not covered yet:

• Link this to [FEAT] Build with support for the new web UI #276 by adding Closes #276 and complete the PR template, including how it was tested
• Apply the same changes to Dockerfile.aarch64
• Put npm in the correct alphabetical position in the package list
• Add a changelog entry to readme-vars.yml

Have you already built it and confirmed that /gui loads? We're using the amd64 image and can test a build if useful.

I built it, I'm using it, it works. Already gone back to the legacy UI if I'm honest.
Can't test arm.
Closes #276
