feat(botfights): 1.2.7 — server-side AI bot (poll mode) + Latest Bouts short-viewport fix

Bumps to botfights:1.2.7, which carries the botfight repo's new
"let BotFights answer for me" feature (ca5b634) — an operator can paste an
Anthropic or OpenAI API key so this node's BotFights server answers fight
challenges automatically for a poll-mode bot, no external script needed.
Storage/security follows the same pattern this node already uses for its
own AIUI Anthropic key (system.settings.set "claude_api_key" in
core/archipelago/src/api/rpc/system/handlers.rs): 0600 file, never echoed
back. Also carries the nostr-provider.js 404 fix, DocsPage/round-jump
fixes, and the HomePage "Latest Bouts" short-viewport visibility fix from
the prior 1.2.4-1.2.6 iterations that were built and tested locally but
not yet pushed through the signed-catalog path.

No archy-side manifest changes beyond the version/image bump — 1.2.2's
ARCHY_EMBEDDED/ARENA_UPSTREAM_URL/generated JWT_SECRET are unchanged;
the new AI-bot feature's key storage lives entirely inside the botfights
app's own data volume, no new archy secret/env wiring needed.
