add default cache-control headers for module web files

[christianvogt]

fixes https://redhat.atlassian.net/browse/RHOAIENG-52182

Back port of #6632 for cache-control headers.
Back port a small change from #5080 for moduleFederation.js

This backport is to prevent cache related issues which occur after an upgrade.

Tested against 2.25.3 cluster with image build from local changes.

• Confirmed presence of cache-control: no-cache header on requests made to /_mf/.
• Confirmed modules, such as model-registry, load correctly.
