fix(webapp): let the webhook deliveries table scroll

The deliveries list passed stickyHeader, which switches the table container to
overflow-visible and so stops it being the scroll container. Every other list in
the app (runs, sessions, batches) leaves it off and renders the table directly in
the layout's content row. The header stays sticky regardless, because TableHeader
always sets sticky top-0.
