feat(supply-chain): 新增替换款规则每日同步定时器安装脚本

SupplyChainProductArchiveReplacementRule 的上游是 rpt.pm_replacementManage，
此前只有 local-sync-archive.mjs 会调用 sync-product-replacement-rules.ts，
正式机没有任何定时任务，表建好后仍然是空的，SABC 的「同款商品编码」也就一直是空。

新增 install-product-replacement-rule-sync-timer.sh，按仓库既有 install-*-timer.sh
同款写法安装 furniture-product-replacement-rule-sync.{service,timer}，
默认每天 07:40（Asia/Shanghai）同步一次，早于 09:00 的 SABC 打标日结。
脚本仅安装定时任务，改动生产数据由 sync-product-replacement-rules.ts 自己完成。
