Fix layout remounts

What are you adding?

Change layout type ReactNode to LayoutsEnum as we ran into compiling error while using the layout property inside any nestedRoutes property. The reason behind this is I think there is a high chance to use this component (e.g setting.routes.ts or home.routes.ts with nestedRoutes property) inside any layout component before it's going to export. Although it's not that usual to change the layout on nested routes, there is an option to change that if anyone wants to. Just to avoid errors updated this configuration
Uplift the Layout component and determine any layout changes at every route change
When an unauthenticated user tries some unknown routes, the user is presented with the default 'HeaderLayout'. Fix this as well
Add NotFound component to nested routes
