Resolve the ACTUAL charged amount (in µ$) from the event when the model is payload-reconciled (C026), else
undefined. Reads the runtime amount-expression (e.g. the Stripe event amount) and converts from its declared unit
— so the recorded cost is the third party's real invoice line, not the operator's declared estimate.
