fix(mining-app): 自动更新检查未触发 — 修复双重节流 + 添加调试日志 

问题原因:
1. checkForUpdate() 未传 force:true，被 UpdateService 内部的60分钟
   SharedPreferences 间隔二次节流，导致实际请求被跳过
2. 缺少日志输出，无法诊断检查流程是否执行

修复:
- checkForUpdate(force: true) 跳过内部60分钟限制，
  因为 MainShell 已有自己的90-300秒随机冷却节流
- 在 initState / dispose / didChangeAppLifecycleState /
  _checkForUpdateIfNeeded 各关键节点添加 debugPrint 日志，
  方便 flutter run 控制台追踪完整检查流程
