 * Truck detention support.
 *  - last_mile.arrived_at / delivered_at: the detention window for an EDR
 *    last-mile vehicle. The clock runs from arrival at destination; the customer
 *    has a grace period (default 3h) to clear/return, after which detention
 *    accrues per truck per day until delivered_at (or now, if still out).
 *  - warehouse_fee_rules.free_hours: configurable grace window (hours) for a
 *    TRUCK_DETENTION_FEE rule; null/0 falls back to the 3-hour default.
