Switch to SmartRes Result/Error, upgrade to .NET 10

Migrate codebase to use SmartRes Result<T, Error> (and Unit) across services and interfaces, replacing previous Result usage and updating many method signatures and implementations. Add ResultExtensions to convert SmartRes results to ASP.NET ActionResult and refactor AuthController to use functional Bind/Tap chains for registration/login flows. Upgrade projects to .NET 10 and bump related NuGet packages; add libs/SmartRes.dll and project references. Simplify DbContext registration to use Npgsql only with retry policies and enable detailed logging. Update Swagger/launch settings and other minor fixes (AutoMapper registration change, whitespace/exception handling, and removal of the Govor.ConsoleClient files).
