+- 签名列表候选范围为截至所选日期的近30日，截止日当天没有发送但此前29日有发送的签名仍须出现。签名详情按“签名 × 消息最终归属通道 × 号码运营商”展示近3/7/30日的发送业务条数、到达业务条数和到达率。业务条数以`SmsMessageRecord`为唯一计数单位，长短信分片和同一短信的通道补发尝试不得重复放大；到达率为到达业务条数除以发送业务条数，分母为0时显示0%。
+- 点击任一通道、运营商和周期组合的“查看趋势”，必须展示该周期每个自然日的发送业务条数、到达业务条数和到达率折线；无数据日期补0，首尾日期与所选周期严格一致并包含截止日当天。数据必须来自真实后端和PostgreSQL，不得使用Mock、静态数据或localStorage。
