			客户往来（回款台账主表）：
			应收金额 = 各销售台账的应收金额之和，
			单条台账应收金额 = 该台账已出库金额 − 已退货款 − 已回款金额（不小于 0）。
			即「回款金额」是累计回款，「应收金额」是还没收回来的部分。
			注意出库金额 = sum(出库数量 * 6位小数的含税单价)，会带有「分」以下的零头，
			而回款是按分录入的整数金额，两者相减会出现 0.0045、0.004 这类无意义的尾差，
			因此单条台账的应收金额按分计算，分以下的尾差不计入。
			注意必须先按台账算好应收、再按客户汇总（与 customewTransactionsDetails 口径一致）。
			若先按客户汇总再取整，各家台账的尾差会累加，出现「主表 0.01、明细全是 0」的对不上问题。
			注意 ★ 出库金额按「销售明细的含税总额」折算，不能直接用「出库数量 × 含税单价」：
			出库金额 = Σ ROUND( 该明细含税总额 × LEAST(1, 该明细已出库量 / 该明细销售数量), 2 )
			原因：销售数量可能带 3 位小数（如 47.328），而出库数量按手册 §5.6 只保留 2 位（47.33）。
			直接相乘得 47.33 × 172 = 8140.76，而开票金额是 47.328 × 172 = 8140.42，
			凭空多出 0.34 的应收 —— 实测黑龙江北盛壶关分公司 13370.02 已全额回款，
			页面上却仍显示欠 0.34。
			· LEAST(1, ...) 用来封顶：出库量 ≥ 销售数量时最多算整条明细的开票金额，超发不增加应收；
			出库量 < 销售数量（部分发货）时按比例计。
			· 每条明细单独 ROUND 到分，避免 0.095 这类分以下零头累积成应收。
			注意出库金额按台账 (sales_ledger.id) 聚合，同一发货单多批号出库时不会重复计数。
