Enabling the invoice-dunning built-in suppressed the legacy reminder ladder
but only created runs for invoices sent AFTER enabling — already-sent unpaid
invoices got dunned by neither. Now:
- Turning dunning ON enrolls every open sent/overdue unpaid invoice via
emitWorkflowEvent('invoice.sent') (engine.backfillDunningRuns(), wired into
the workflow enable toggle). Idempotent via the per-(flow,entity) dedup.
- The grace wait is anchored to the invoice's due date: computeWakeAt now
treats { untilVar, delayDays } as "var + offset" (was var-only OR now+offset),
and the built-in's waitGrace becomes { untilVar: 'dueDate', delayDays:
firstDays } (seed v6 -> v7). An already-overdue invoice duns on its real
timeline instead of restarting a fresh grace clock.
Note: the due-date-anchored graph applies to freshly seeded built-ins; an
already-admin-enabled dunning workflow still enrolls via backfill but keeps its
current grace timing until re-seeded.
