Add DynamicLayoutComponent to the root level as a layout

[mehmet-erim]

The DynamicLayoutComponent should be added to the app-routing.module.ts as shown below:

// all routes should be a child of the DynamicLayoutComponent
const routes: Routes = [
  {
    path: '',
    component: DynamicLayoutComponent, // should be defined at root level
    children: [
      // other routes
    ], 
  },
];
