Checkout recovers from dropped connections and clearer card errors

A shopper whose device loses its connection during checkout used to see a generic error with no way to know if the order actually placed. Checkout now shows a clear message and a "Check if my order was placed" button that looks up a matching recent order, so you don't re-submit and risk a double charge.

Card declines now say the card was declined instead of showing a vague failure message. The error names the problem so you can fix it or try a different card.

Offers product lists now group each service and add-on under its parent product with the same tree-line layout used on order detail, instead of a flat list where it was unclear which service belonged to which product.

Buscar can now answer questions about a past month's on-hand inventory at a Field location, returning the correct reconstructed quantity instead of a wrong number or a refusal.
