feedback1 WB: special-refresh offers drawn as what they hold (凯瑟琳's three items as item cards)

Player report #6: 凯瑟琳's 定向投放 offer after a level-up showed three nameless
operator cards (the raw item ids) under the promotion reward's 晋升奖励 header.
The shop bar now draws each offer slot by its kind (item slots as free item
cards) and names the offer: m.private shop.rewardOffer carries source
('merge' | 'special') and label (the strategy's effect name, the item's name
or the 特质's operator — effectsMeta.offerLabel); the reminder pill says
<label>待选择. Same path for 娜仁图亚, 寻呼模块, 信标 and 松果.
