/// L0 生产 loader：实现 <see cref="IIqcReceiptStateLoader"/>，从标准层 <see cref="IIqcReceiptStdReader"/>
/// 组装 <see cref="IqcReceiptState"/>。**只读 mdp_std**，不直连源库/旧表。
///
/// 计算口径（B6：由事实读时计算，不存易过期布尔）：
///   HasPendingReceipt = ReceiptPendingQty &gt; 0（PurOrdDetail.ReceiptQty）
///   HasReceivableDetails = ReceivableDetailCount &gt; 0（MissedPrint Status='N'）
/// UNRESOLVED（不猜测）：
///   Refs → 恒空 ""（收货上下文无此列，与库存层默认一致）；
///   新收货号 → 写侧 pr_SFM_GetOrdNbr 生成；本 loader 供既有收货号 RctNbr(=PurOrdRctDetail.Receiver)。
/// freshness：透传 SourceSyncedAt(=sync_time)，由消费端与事件时刻比对（见 B8）。
