feat(backend): F1-6 sprint2 #1 60d 消费迁移到 sandbox_replay

迁移 fdw_queries.get_consumption_60d 到 sandbox_replay.consumption_replay,
沿用 sprint 1 模式: @trace_service + @runtime_aware decorator + 显式
stat_date <= ctx.business_date 上界(与视图过滤双保险),fdw_queries 改
thin wrapper 保持 customer_service 2 处调用兼容。

双口径走查 PASS(member=2799207087163141 黄先生):
- 4a live(today=2026-05-05): 小程序 stat 卡条 60天消费 ¥115(consume_amount_60d=115.36)
- 4b sandbox=2026-04-20: 小程序 stat 卡条 60天消费 ¥89(walkthrough 测试快照 88.88)

unit test sprint1+sprint2 累计 15/15 PASS,无回归。
