Converted the Messaging.vbproj project file to the modern SDK-style format targeting net8.0-windows, enabling Windows Forms and implicit usings. Replaced direct assembly references and the old packages.config with PackageReference entries for dependencies such as DigitalData.Modules.Logging, Microsoft.Identity.Client, Microsoft.IdentityModel.Abstractions, NLog, and S22.Imap. Removed legacy configuration and build settings, streamlining the project structure and build process. Deleted the obsolete packages.config file.
