list_codes
List prop firm discount codes ("coupon codes" / "promo codes" to a user). Each code works any time; the validity window is a procedural calendar-year label, not an expiry. Filter by firm name, active-only, or minimum discount. Present results as discount codes — never as "standing codes".
