Per-processor certification override knobs. These are <strong>cert-only</strong> escape hatches
for forcing network-request indicators that production traffic never needs. Examples include
flipping a card-present transaction to card-not-present routing for a specific cert scenario,
or supplying a hard-coded scheme transaction id for a Visa MIT cert flow.
