Add the cart to an existing delivery instead of blocking it on the new-order minimum ... f856cd3a2d

The app has no separate request for "Zur Bestellung hinzufügen": it sends the
same checkout start, payment and confirmation, and leaves the minimum order
value to Picnic's answer (PRICE_TOO_LOW). The preview applied the slot minimum
itself and so refused a 1249 cent addition to a current delivery.

The preview now reads the current deliveries and reports a mode. When exactly
one current delivery uses the cart's selected slot, it names that delivery, its
orders and the additional amount, and the minimum only warns. New orders keep
the minimum blocker. Unclear cases are blockers, not guesses.

picnic_checkout_add_to_delivery commits an addition. Its token is bound to the
mode, the delivery and the order ids in it, so it cannot become a new order and
picnic_checkout_place_order refuses it. Success is reported only when the new
order id is read back in the target delivery.
