fix: get_delivery_invitation_by_token returns full order composition with items
RPC was returning only top-level invoice numbers (nom) without the nested
product items inside orderList[].items[]. Now returns {name, quantity, items}
structure matching flattenOrderProducts() expectations in OrderCompositionPanel.
Before: orderItems = [{name: 'ТП-008590', quantity: '1'}]
After: orderItems = [{name: 'ТП-008590', items: [{name: 'СФ Т\ЕА-28944', items: [{product_name, product_quantity, product_ed}]}]}]
Also includes stop words, delivery type, pickup code, payed_ship fields.
