// specific entitlement — course_subscription_access/required_active_tier/
// group_restriction/item_allowlist rule types, plus the "starter-set purchase
// eligibility" gate derived from item_allowlist) has been removed entirely,
// admin UI and runtime enforcement both — item-specific `user_tier_grants` is
// the only entitlement mechanism now (see hasItemGrant() in
// controllers/client/courses.controller.js). No other table has an FK into
// plan_policies (only plan_policies.plan_id -> tier_plans.plan_id), so this
// is a clean, isolated drop.
//
// NOT auto-run — do not execute against the shared dev/prod database without
