Add logic to initialize at least one user if the startup wizard is not completed, both during application startup and in the startup user API. After user creation, reload the user entity with all related navigation properties to ensure the in-memory user object is fully populated. Also update build and publish metadata files.
Refactored all C# test files to use explicit namespace declarations and moved all using directives inside the namespace block for consistency. Updated assembly info and cache files to reflect the new build. Adjusted MvcTestingAppManifest.json to use fully qualified assembly names. No functional changes; all updates are related to code style, organization, and project metadata.
