Reorder queue creation form to prevent vhost reset

When creating a queue in the management UI, selecting a non-`/` virtual
host, then a queue type different than the default for that virtual host
causes the vhost selection to reset to `/`. This happens because
changing the queue type calls `update()`, which re-renders the entire
form to display specific data for that virtual host, losing the user's
virtual host selection.

This change reorders the "Add a new queue" form fields so that "Type"
appears before "Virtual host". Users now select the queue type first,
triggering the form re-render before they make their vhost selection.
This prevents the vhost reset without requiring JS wizardry/hacks to
preserve form state across re-renders.
