/**
 * 微信订阅消息的授权记账表。
 *
 * 为什么需要它：微信**不提供**「这个用户还剩几条订阅授权」的查询接口，
 * 而「一次性订阅」是发一条扣一条。所以这里按 (userId, templateId) 记账：
 * 用户在小程序里点「允许」时 grantedCount +1，服务端发送成功时 sentCount +1，
 * 被微信拒绝（如 43101）时 blockedCount +1 并记下 errcode。
 *
 * ⚠️ 这里算出的额度是**我们自己数的近似值**：用户可能在别处授权、或微信侧额度
 * 过期，真值只有发一条收到 43101 才知道。所以 `no-grant` 预检只用于「省一次请求」，
 * 不能当成权威判断（自测接口用 force 绕过）。
