/**
 * Settles a submitted payout (SUBMITTED to SETTLED), driven by the provider's settlement report.
 *
 * A system-actor operation, so the provider's inbound webhook can trigger it. The worker sweep
 * never settles; it only re-drives and force-fails stale payouts (src/worker/payouts.ts).
 * Restricted to system or operator (RESTRICTED_TO_PRIVILEGED in economy.ts): an end
 * user must never settle their own payout. Losing the SUBMITTED to SETTLED CAS rolls back the two
 * postings and the event, so the seller is never paid twice.
 *
 * @see {@link https://economy-lab-docs.pages.dev/economy/reference/operations/settle-payout/ Settle
 *   payout} for the webhook-driven SUBMITTED to SETTLED settlement step.
 * @see {@link https://economy-lab-docs.pages.dev/economy/ports/processor/ Processor} for the
 *   settlement and dispute callback contract.
