chore(catalog): sign app-catalog — BotFights 1.2.3, mode-picker guide fix

releases/app-catalog.json regenerated and signed by the release-root key
(did🔑z6MkkidEnEpo6qHMCNSZoNKWtvQvxq3whnaME9wGgEFhq7ur). botfights is
the only content change vs the previously-published catalog (verified
structurally — all other 65 apps unchanged): 1.2.2 -> 1.2.3, carries the
JoinBoutPage.vue setup-guide mode-picker UX fix on top of 1.2.2's
ARCHY_EMBEDDED iframe fix and 1.2.1's JWT_SECRET/arena-federation fixes.
