siddharthd 79940202f1 orders: fix the 42703 that broke EVERY order detail page
getOrderDetail joined order_merchant_cadence on merchant_entity_id. Migration
021 rekeyed that view to merchant_key (merchant_entity_id is NULL on ~9% of the
feed, and duplicate merchant entities split one shop's history); 027 and 029
moved order_feed and order_spend across, and this query was missed. Every
/orders/<key> request has since failed with

  column rec.merchant_entity_id does not exist

The reason nobody saw a 500 is the second half of this commit: the page
collapsed every failure into 'That order could not be found.' A server fault
wearing the costume of a data condition reads as an empty spine and gets
investigated in the wrong repo. The hook now carries the status and only a
genuine 404 says the order is missing.
