refactor(activity): 全面优化 LoginByFaceActivity 代码质量

- 移除静态 instance 引用，消除潜在内存泄漏风险
- Observer {} 显式包装统一改为 Kotlin lambda 写法
- 匿名 Debouncer 改为成员变量 openDebouncer（修复防抖失效 bug）
- Thread.start() 替换为 lifecycleScope.launch(Dispatchers.IO)
- Arrays.fill() 替换为 Kotlin ByteArray.fill()，移除 Java import
- 清理死字段：regDebouncer、faceUseSwitch、faceFailThreshold、tempUserId
- Java getter 语法统一改为 Kotlin 属性访问
- 移除 protected override、无效 handleLoginSuccess override 等冗余代码
- 顶部添加 @file:Suppress("DEPRECATION") 统一处理废弃 API 警告
