Legacy never posted order debt; updateRemain recomputed it as
SUM(orders.input) WHERE sts > 4. The port posted it once on entering
DELIVERED_TO_AGENT, guarded on deliveredAt, which:
- posted it twice when an order reached that status again
- posted nothing for an order sent straight to DELIVERED_TO_CUSTOMER
- kept it after a rollback or cancellation
syncOrderDebt compares what the order should owe with the confirmed
ORDER_STOCK entries on it and posts only the difference (append-only,
idempotent). Status removal runs it too, so removing «تحویل به نماینده»
is allowed again, as in legacy. Existing data: 0 orders out of line.
