fix(welfare): review 修复 — 里程碑"暂不发金币"文档同步 + 消息提醒奖励降为 1000

- comparison_milestone: 删 record_milestone_reward 死导入(ruff F401), 模块 docstring 同步"暂不发金币"
- 里程碑文档群对齐实现: compare-milestones / comparison_milestone_claim / MilestoneStateOut.coin 描述都标注暂不真发金币
- models/comparison: comparison_results JSONB 形状注释补 coupon_saved
- enable_notification 奖励 10000→1000(产品定, =¥0.1); test_exchange_flow 改 grant_coins 直接供款(不再靠该任务=兑换下限)
