Add tile-specific URL field to App API
This will allow us to point the tile's button to a place that's different than the main URL of an app. The only practical example for this right now is Wordpress -- it is more logical for users to want to go to the admin page than to visit their own website from the dashboard.
For whoever will be taking this ticket in the future: remember that the wordpress tile currently injects /wp-admin
into the URL, line 101 on frontend/src/modules/dashboard/components/DashboardCard/DashboardCard.tsx
at the time of writing.
