Converted Database.vbproj to the modern SDK-style project format targeting .NET 8.0, replacing explicit assembly references and the use of packages.config with PackageReference entries for dependencies such as EntityFramework, Firebird, NLog, and System.Data.Odbc. Removed legacy MSBuild properties, imports, and targets, and deleted the obsolete packages.config file. This streamlines dependency management and modernizes the project structure.
