Verification pass found three tests only guarded correctness, not the fix's
behavior:
- H7: add repository white-box test asserting likes/replies come back as
initialised PersistentCollections (lazy without the fetch-join).
- H8: add a query-count test (constant vs coverage-row count) — without the
batch fetch the count grows ~1 per row.
- H5: add an end-to-end test hitting DELETE /api/v1/doctor and asserting the
insurance config is purged (the service unit test didn't cover the wiring).
All three now fail when their fix is reverted. Suite: 39 tests / 92 assertions.
