feat: Automatically get explained response if URL can be provided

Did you try this with an actual https://github.com/fedora-copr/logdetective ? I haven't yet, but my suspicion is that this will show the "Getting a response from the server" line forever. The query-url will be defined even after we receive the data from the server, so we will go back here, instead of going to the else branch (the whole cond expression).

Still haven't tried with the actual logdetective service, but I think I am right. The send function defines these two handlers:

logdetective-website/frontend/src/app/prompt/core.cljs

Lines 68 to 82 in 13a7827

	:error-handler
	(fn [error]
	(handle-backend-error
	(:error (:response error))
	(:description (:response error))))
	:handler
	(fn [data]
	(if (m/validate InputSchema data)
	(do
	(reset! status "ok")
	(reset! form data))
	(handle-backend-error
	"Invalid data"
	"Got invalid data from the backend. This is likely a bug.")))))

If you put (js/console.log "Hello") or (js/alert "Hello") in them, you can see that the response handled almost immediately (in my case) but the page still shows "Getting a response from the server"
