feat: auto-populate yard and zone from selected warehouse

When warehouse is selected in standalone return modal, yard and zone
fields are automatically populated from warehouse data (yard from
warehouse.yard or warehouse.code, zone from warehouse.zone). Fields are
read-only/disabled to prevent manual editing.
