Add IP info & flag emoji to test，add ip info column for main window

Fetch and display tested server IP and country (with emoji) in speed tests. Adds CountryExtension for country->emoji mapping and a new IpInfoResult type; ConnectionHandler now retrieves/parses IP API results and GetRealPingTime signature adjusted. Models and entities (ProfileItemModel, ProfileExItem, SpeedTestResult) gain IpInfo fields; ProfileExManager can store test IP info. UI/UX updated: new IpInfo column in ProfilesView (desktop and Avalonia), ResUI resource strings for "IP Info", and EServerColName ordering supports IpInfo. SpeedtestService now captures IP info and forwards it to the view model via the update function.
