Order.order_number tildeles atomisk i POST /public/orders via en
SELECT ... FOR UPDATE-lås på rundens række + MAX+1, så samtidige
bestillinger lige efter en runde åbner ikke kan kollidere. Nummeret
starter på 1 for hver runde (UNIQUE(purchase_round_id, order_number))
og er nu tilgængeligt som {{order_number}} i mail-skabeloner.
GET /purchase-rounds/{id}/pickup-list genskaber den gamle systems
afhentningsliste (delt af brugeren som reference) mod den nye
datamodel: én printside pr. ordre, sorteret efter order_number (vist
stort i øverste højre hjørne), kontaktinfo, flaske-/kasseantal
(pænt afrundet — originalen viste et urundet float), og
vinlinjer grupperet pr. kategori.
