For the record: I fixed the problems now. JS now loads correctly in Jenkins and
in Jenkins test harness.
I needed to initialize the variables ${resURL} manually in each Jelly file:
<j:new var="h" className="hudson.Functions" />
${h.initPageVariables(context)}
Then the new UI JS plugins can be simply referenced by using an adjunct like
<st:adjunct includes="io.jenkins.plugins.bootstrap4“/>
This resolves all JS and CSS files below
${resURL}/plugin/bootstrap4-api/*
An example of such a view is available at
https://github.com/jenkinsci/forensics-api-plugin/blob/1da271633a776e9fcee586861414a20f726ffd38/src/main/resources/io/jenkins/plugins/forensics/miner/ForensicsViewModel/index.jelly

I will prepare a blog post that introduces these new JS plugins in the next
couple of weeks…
