checkForceRechargeRequirement() 新增层级逻辑:平台(PackageSeries)的强充配置具有最高优先级;平台未设强充时,读取 order.SellerShopID 对应的 ShopSeriesAllocation 强充配置;两者均未设时返回 need_force_recharge=false(降级处理)。GetPurchaseCheck 复用同一函数,无需额外修改。 Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-opencode) Co-authored-by: Sisyphus <clio-agent@sisyphuslabs.ai>
