Billing and cost controls

This actor uses fixed-inclusive pay-per-event pricing. It charges actor-start, then page-audited before each dataset row, and audit-report-generated before report artifacts. maxChargeUsd is enforced locally and in Apify runs; uncharged rows and reports are withheld. Platform usage pass-through remains off.
