/**
 * 每日商店数据层（Battlebuff 表）：
 * - 按日刷货架 3 格 + 抽奖 8 格（权重、不重复；仅 roll 时排除已携带）
 * - 商品池仅在胜利结算 refreshPoolsOnSettle 或凌晨跨天 applyDayResetIfNeeded 时重抽
 * - 凌晨跨天重置仅在登录 / 胜利结算 / 失败结算时触发，对局中过零点不重置
 * - 购买/抽奖入槽后不剔除池内商品、不补抽；手动 refreshOffers 只重置次数
 * - 携带槽位数：ConstConf 78 constgroup[0] 主动、[1] 被动
 * - 购买成功即写入携带（或即时类直接发奖），供战斗侧读取生效
 *
 * 存档格式（OtherDataType.DailyShopState，禁止下划线）：
 *   day|offers|passive|active|sold|offerAd|pending|pendingAd|lottery|lotteryUsed|lotteryTabOpen|openGold|openAd|openGuide
 * 空槽用 0；offerAd 为 1 表示该格广告购、0 表示铜币购（Const 21 权重决定 0~2 格广告，随机分配）。
 * 入槽 id 为 Battlebuff.id + BATTLE_BUFF_STORE_OFFSET（10000）。
