refactor(ui): drop the direct and last-route chips from the route tab

The "used when direct" chip marked the provider the client falls back to
after leaving routing. It only helps on the direct tab, where "back to
direct" acts at once and doesn't name the provider. On the route tab
nothing acts on that provider, and with failover on the chip only showed
up when the provider happened to be outside the queue.

The "last routed" chip in the route preview said which provider "start
routing" would use, but the confirm dialog already preselects and shows
it.

Keep the direct chip on the direct tab only and remove the other one
together with its string.
