Subject: [PATCH] test(config,profile): lock 'ko/ko_kr no longer accepted'
 contract

After the i18n catalog shrink, ko/ko_kr fall into the strict-reject
path of cmdutil.ParseLangFlag. Pin that with explicit test cases on
all three --lang entry points so future catalog edits can't silently
re-expand the supported set.
