feat(ingest): read a summoning campaign as a banner

Every game names its gacha something else, and inferType only knew the
five words the game8 sources use. Fate/Grand Order calls its banners
"Summoning Campaign" — the whole of that page's banner vocabulary — so
without this every FGO pull lands as "other" and the type filter stops
meaning anything for that lane.

Nothing on the current English page carries the word, so no checked-in
expected output moves; the unit case is what pins the behaviour until
the next refresh brings a banner in.
