feat(ops): 错误日志 key 归因与早退字段补全

让 /admin/ops 错误详情正确归因 API key 并补全早退场景字段，合并三项改动:

- 鉴权早退补全用户/分组/平台字段:引入 ops fallback key(ContextKeyOpsFallbackAPIKey),
  apiKey 一加载成功即写入,覆盖分组停用/删除、Key 停用/过期/额度、用户停用、IP 限制等早退
  路径;ops 错误日志改用 getOpsAPIKey(正式 key 优先、回退键兜底),不改「已鉴权」语义。
- 已删除 key 归因(迁移 145):删除 key 时同一事务写 deleted_api_key_audits 映射,认证失败
  时用明文反查命中原所有者,错误详情展示「已删除 Key 所有者」「尝试的 Key 前缀」。
- 有效 key 报错快照前缀(迁移 147):对绑定有效 key 的错误,落库时快照明文前 8 位到
  api_key_prefix(与 attempted_key_prefix 互斥),key 之后被删仍保留报错当时真实前缀。

均仅对上线后新产生的错误/删除生效。
