[pennane]

Add some settings view that has the already made auth components.

The view should be accessed from the right side of the nav bar.

Possible implementation

• Uus file: app/src/Views/SettingsView/index.jsx

• Lisää app/src/main.jsx routeriin uus route esim("/settings") joka vie Toho uutee filuun

  const router = createBrowserRouter([
  {
  path: '/',
  element: <RootLayout />,
  errorElement: <NotFound />,
  children: [
    {
      path: '/',
      element: <MainView />
    },
    {
      path: '/posts/:id',
      element: <PostView />
    },
    {
      path: '/settings',
      element: <SettingsView />
    }
  ],
  }
  ])
