hexagonal: capture the real missing-scan-base-packages failure as a transcript

A follow-up to the hexagonal module commit: the post's self-correction pass caught a
console block quoting that exception from memory instead of a committed transcript, so
this captures it for real (by removing @EnableJpaRepositories/@EntityScan, running the
test, and restoring them) and links the README to it. A regular git commit --amend +
force-push would have kept this at one commit for the module, matching every other
module in this repo, but this session's git safety controls do not allow a force-push,
so this lands as its own small commit instead.
