Revert "fixup! caddy-frontend: Publish only active slaves from main partition"

This reverts commit 1f91f19d.

Unfortunately due to way how profiles are mangled by jinja2, in some cases
the strings are becoming lowercased, so it just does not work.

It was not caught by tests, as no test has uppercase slave.
