Feature: add client log dialog with auto-refresh, icon and menu bitmap

- CClientLogManager: push thread sends incremental logs every 3s; join() instead of detach() prevents use-after-free on shutdown
- CClientLog::OnReceiveComplete: handles TOKEN_REPORT_LOG on IOCP thread via PostMessage, fixing incremental packets being silently dropped
- Dialog icon (ClientLog.ico) and menu bitmap (ClientLog.bmp) added; OnInitDialog loads icon; IDR_MENU_LIST_ONLINE "运行日志" item gets the bitmap
