// Tier Plans v2: bundle items (courses/units/lessons) may now belong to more
// than one plan simultaneously — the old single-column unique constraints
// enforced "one item = at most one plan ever", which blocks that. Replace
// each with a composite unique on (plan_id, item_id), which still prevents
// the same item being added twice to the *same* plan.
