Boot self-heal seeds the corrected gate-in-loop dunning graph (wait→due,
grace wait, invoice_paid check, confirm-no-payment gate, bounded reminder
loop with re-check, final notice) keyed on builtin_key='invoice_dunning',
sized from the reminder_first/second_days settings. Seeded DISABLED and
is_builtin: live reminder behaviour is UNCHANGED (the hardcoded scheduler
ladder still runs) — enabling it pre-cutover would double-send, so the
engine cutover is a deliberate follow-up. Idempotent (preserves admin edits).
Built-ins refuse delete (enforced in the CRUD route). Test covers seed shape
+ idempotency.
