refactor(logger): 日志改用 logrus 全局包级调用，移除 Logger 注入接口

为什么：并入宿主项目后须与宿主日志体系一致——宿主统一用 pkg/logger 初始化
logrus 全局实例并直接 logrus.Xxx 包级调用；包一层 Logger 接口会让 logrus 的
caller 定位（报告调用文件:行号）失准。

改动：
- 删除 logger 包（Logger 接口 / Default / SetDefault，默认本就是 logrus.StandardLogger）
- 11 个结构体移除 lgr logger.Logger 字段、SetLogger 方法及构造中的 lgr 初始化
- 192 处 lgr.Xxxf 调用改为 logrus.Xxxf，日志消息文本保持不变
- xiaomi.Client 移除 Logger() 访问器，air_conditioner 回读日志去掉判空调用直连 logrus
- miot_i18n.go 两处标准库 log.Printf 改为 logrus.Errorf，统一日志出口
- go.mod：logrus 从 indirect 提升为直接依赖
- goimports/goformat 全树规范化：此前部分文件未 gofmt（单行 if、对齐），本次顺带
  格式化，纯空白/换行变化，无逻辑改动

验证：go build / go vet / go test ./... 全部通过（bridge、miot、xiaomi、devices、specs）
