order details: hide the review surface for spine-bridged retail rows

Verdicts are the meal lane's feedback loop (loved/never steers the next
restaurant order and the nudge card warns on re-order). Bridge rows
(source='order-bridge': Amazon, eBay, Officeworks...) have no such loop,
so ItemVerdictToggle and OrderVerdict stay hidden there. The order API
now returns 'source'; OrderReceipt.platform widened to string — the
bridge writes real platform slugs beyond the meal trio.
