TestWebSocketUserScopedBroadcast creates "Admin Collection <uuid8>" on
the shared admin — deliberately NOT named with "test" or every run
would 409 on UNIQUE(user_id, name) against stranded past-run rows
(the comment in the test says exactly that), but it never deleted its
row, so the same runs accrued ten "Admin Collection" forever-rows the
name sweep can never touch. cleanupCollectionByID gives tests an
owner-scoped RLS-bridge delete-at-backstory: same minimal contract as
cleanupDeviceByIdentifier, for rows whose name must stay unique across
runs. Deleted the ten standing rows (owner-scoped, exactly what the
cleanup path does).
What CANNOT be swept, audited safe: the dev admin's real hand-made
collections (Saga reading-orders, Podcast 2, Smart Collection (Books))
carry no sweepable names; devices rely on identifier/token prefixes
tests own exclusively; the rls-phone hand account persists because the
transient-user sweep matches only @tests.bookhoard.internal /
@example.com emails.
