Struct DeliveryCancelItemRow 

pub struct DeliveryCancelItemRow {
    pub item_id: Uuid,
    pub quantity: Decimal,
    pub cogs_amount: Decimal,
}

A delivery line as the CANCEL path reads it: the stored cogs_amount is the exact value the outflow consumed (for the drain-to-zero line, the whole remaining value) — the cancellation restores that exact amount, so the bin reblends to its pre-delivery state.
