feat: 新增 SMTP/IMAP/POP3 协议调用日志(含攻击分析筛选)
- 每个连接记录一条日志:协议、端口、来源 IP、用户名、成功/失败、 失败原因(密码错误/IP封禁/中继被拒/发件人伪造/未认证发信等)、 操作摘要、消息数与会话时长 - 管理后台新增「协议日志」页:按协议/状态/IP/用户名/时间筛选, 今日与历史成功/失败统计卡片,分页查看,可手动清理 - 后台每 6 小时自动清理超出 protocol_log_keep_days(默认30天) 的日志;新增 [web] protocol_log_keep_days 配置项 - 修复 POP3 认证既有 bug:handleUSER 丢弃邮箱域名导致 PASS 永远失败 - 新增 store 单测、SMTP/POP3 端到端测试与模板渲染测试
