Give a syndicated offer a title a stranger can read

A campaign's name is the member's own internal label, and some of them are
two characters ("MG"). DripOffers rejects anything under five, and more to
the point a click-earner scanning the offerwall learns nothing from "MG".

So the ad's own headline comes first, then the label, and a very short
label is qualified with the destination host — "MG (mailer.gold)" — rather
than dropped or dressed up in marketing copy we invented on the member's
behalf. Nothing usable at all returns null instead of a made-up title.

Found by the backfill: campaign 88 failed on it.
