/**
 * VIP 后台设置结构化契约（对照参考主题 zibll 1:1）。
 *
 * 硬约束：
 * 1) 会员商品 / 续费商品 / 升级价格 / 积分兑换明细全部为结构化 group 或
 *    accordion，`|` 分隔的 textarea 配置已彻底移除（不写双路/迁移）；
 * 2) 「会员等级」组只留导航按钮与两个等级开关，等级身份字段（显示名称/
 *    简介/权益HTML/图标URL）与「会员商品」同处「会员购买选项」的等级 Tab；
 * 3) 会员商品字段集恰好 6 项：执行价/原价/促销标签/标签颜色/会员有效时间/
 *    时长单位；标签颜色为参考主题 b+jb 全量 16 色；
 * 4) 续费价格类型含「自定义商品」，升级价格为参考主题同款三块 accordion；
 * 5) tag_class 一路透传到前端套餐卡；等级 Tab 标题由显示名称动态驱动。
