"""提醒送达与到期文案测试

覆盖两处回归：

1. Telegram 不能带 parse_mode=HTML：消息里嵌的是资产名/平台名等用户数据，
   含 < > & 时整条消息会被 Telegram 拒收（400），提醒静默发不出去；
   失败时还必须把响应正文带回，否则只看到状态码根本无从排查。
2. days 可以为负（已过期），文案统一走 renewal_service.day_text，
   不能直出「-37 天后到期」；前端对应 Fmt.countdownText，两边一致。

运行：.venv/bin/pytest tests/test_notification.py -v
