-- Profit-control fields are part of the API-key auth snapshot and gate the
-- scheduling admission filter; the profit threshold D additionally depends on
-- group pricing and peak-window fields. Extend the durable invalidation
-- trigger so out-of-band group edits (direct SQL, crash between update and
-- app-level invalidation) cannot leave cached snapshots using stale
-- profit-control inputs. Normal admin saves already invalidate via
-- InvalidateAuthCacheByGroupID; this trigger is the durable backstop. Based on
-- the latest function body from 186_group_auth_cache_image_generation.sql.
