fix(botfights): 1.2.3 — mode-picker guide banner (join-bout UX)

Bumps to botfights:1.2.3, which carries the JoinBoutPage.vue fix from the
botfight repo (commit 603e09b): the poll/webhook mode picker on the bot
setup step now visibly reacts when clicked — a colored banner in the guide
viewer and a prepended line in the copied prompt point at "Option A:
Polling Bot" or "Option B: Webhook Bot" within the single unified doc
(BOT-02), instead of silently refetching the same file with no visible
change. No manifest/env changes beyond the version/image bump — 1.2.2's
ARCHY_EMBEDDED/ARENA_UPSTREAM_URL/generated JWT_SECRET are unchanged.
