Stop the purchase run when an audit write fails.

If the audit log fills or becomes unwritable after preflight, writePurchaseAuditRecord logs a warning and the CSV loop continues purchasing. Those purchases can finish without the records needed to reconcile a partial run. Return the write error to the purchase pipeline and stop further purchases; report the failure to the CLI caller. The pinned audit writer explicitly returns I/O errors, while its writability check only opens and closes the file. (github.com)

Review comment at @cmd/multi_service.go around lines 420 - 422:
Update writePurchaseAuditRecord to return errors from common.WriteAuditRecord
instead of logging and continuing; propagate that error through the purchase
pipeline so the CSV loop stops further purchases and the CLI caller reports the
failure.

Write each CSV audit record before the purchase delay.

For every real purchase except the last in a region, processPurchaseLoop sleeps after executePurchase and before this write. If the process terminates during that delay, the purchase has no audit record. Move the write immediately after the purchase result is available, as executePurchasePipeline already does.

Review comment at @cmd/multi_service.go at line 772:
Move the writePurchaseAuditRecord call in processPurchaseLoop to immediately
after executePurchase returns its result, before any purchase delay, so each
completed purchase is audited even if the process terminates during the delay.
