refactor: 实现第二批 Manager（LogManager/ConfigManager/DialogService/TrainingModeManager）

- log_manager.py: 日志区+进度条+清空按钮封装，内部订阅 LogMessage/ProgressUpdate

- config_manager.py: 配置读写（new/load/save/get_current_config），懒加载安全（未加载面板返回 {}）

- dialog_service.py: 纯展示弹窗封装（Pipeline状态/关于/AI设置）

- training_mode_manager.py: 训练模式切换，发布 TrainingModeChanged 事件

- water_quality_gui_v2.py: 725→605 行，菜单回调全部委托给 Manager，移除 _create_log_panel/_create_progress_panel/_on_log_message/_on_progress_update
