Missing 'Cancel' button on new hw models page
When creating new hw model in UI, there is only 'Submit' button and 'Cancel' is missing.
Fixes #30774 - Show cancel btn on new hw model page
For a link on erb page to be handled by react-router,
it needs to be wrapped with Router component and have
access to react routes. AppSwitcher deals with the logic
for routes and its render function needs to render children
so that wrapped component is displayed on the page.
