/**
 * #6328 (export/backup boundary) — when `hidePaidModels` is on, the settings
 * JSON export must strip paid combo model steps so a round-trip (export →
 * import) does not silently re-materialise the paid targets the operator asked
 * to REMOVE. `filterPaidComboSteps` is the pure filter wired into the export
 * route; `combo-ref` steps and pricing-less combos are left untouched.
 * Rule #18 regression guard.
