2. Check different npm commands to build/run Headlamp to see if it works

It seems one of the CI jobs is failing still, so I put it in draft mode.

When it's working for you, I think breaking this up into separate PRs would be good. To reduce the size and risk. Probably a bunch of your commits are separate enough to do this?

Can you please confirm which platforms you've tested on in the PR?
