feat: add scope to plugin routes and menu items

[dated]

Summary

Multiple plugins that define the same routes can currently result in unexpected routing. For example the following configuration will potentially route to the original ARK Explorer plugin (if installed and enabled):

    this.routes = [
      {
        path: '/my-ark-explorer,
        name: 'ark-explorer',
        component: 'MyExplorer
      }
    ]

    this.menuItems = [
      {
        routeName: 'ark-explorer',
        title: 'My ARK Explorer'
      }
    ]

This PR scopes the plugin routes under the plugin's id. Navigation through the ROUTES permission can still be done without using the scope.
