Wave 2 fix: correct bookWordmark test assertions (casing-only brands + bet365)

The merged suite exposed two self-defeating assertions in 2B's book test:
uppercasing the name before comparing to the key false-failed correct brand
names (DraftKings→DRAFTKINGS), and the lowercase-echo guard rejected bet365
whose official wordmark IS lowercase. bookInfo output was always correct.
