Refactor: centralize grid band layout logic in service

Browse Source 
Introduce BandLayoutService and shared models to manage grid band layouts across components. Refactor CatalogsGrid and MassDataGrid to use the new service, removing duplicated layout logic. Update _Imports.razor and register the service in Program.cs for improved maintainability and code reuse.
