Goal

• Make easier to naviage
• Utilize layout component

Details

Right now all components goes to Components folder. It whould be much easier to navigate if we split em

• Components - reusable small components
• Pages - all components with @page directive
• move App.razor to root
• Layouts - There will be just one MainLayout.razor. Extract all related thing there (NavBar, Header)

Need approve of idea. Will make PR
