feat(store-mapping): JD 缓存 deeplink 失效标记(对标淘宝)

store_mapping 加 jd_deeplink_invalid_at 列 + 迁移(down_revision=store_mapping_tb_dl_invalid);
mark_jd_deeplink_invalid 按 id_jd 标记 + lookup_nearest 过滤已失效 JD 候选;
/internal/store-mapping/invalidate 接 jd 分支。配 pricebot 京东缓存 deeplink 失效回退。

+京东同淘宝: 缓存的店内搜索 deeplink 会失效(打开是"当前门店超出配送范围"页)。pricebot 比价撞到
+失效页时回退正常搜店, 并 server→server 通知把该 storeId 的 deeplink 标记失效。本列记失效时刻
+(NULL=有效); lookup 反查时过滤掉已失效的京东候选, 不再返回坏 deeplink。
+与淘宝 taobao_deeplink_invalid_at 对称; 用时间戳而非布尔: 留痕可审计、可统计失效率, 不销毁原 deeplink。
