/api/v1/utils/users/redis exposed open CRUD — create, read, update and delete
on the cached-user store — to anonymous callers. The store is currently empty
and nothing in the console or apps calls it, so closing it breaks no client.
Third of the three route groups flagged in the 2026-07-27 audit. /crm/* stays
open by explicit decision: the field-sales Flutter app sends no credentials.
