Subject: [PATCH] Ensure history items have valid icons in QueryHistory

Added CheckIcoPathValidity to QueryHistory to set default icons for history items missing IcoPath, addressing legacy data issues. Integrated this check into MainViewModel's RefreshLastOpenedHistoryResults to guarantee icon validity before updating absolute paths.
