Refactor startup user creation and add HomeSection config

Refactored user initialization to always ensure at least one user exists at startup. If no users are present, a default admin user (admin/jellyfin) is created automatically. Updated StartupController endpoints to handle cases where no user exists. Simplified UserManager.InitializeAsync logic. Added HomeSectionConfiguration for EF Core entity mapping. Includes minor project and assembly info updates.
