feat(botfights): 1.2.9 — Cashu primary entry-fee UX, anonymous-bot ranked staking

Bumps to botfights:1.2.9, which carries: Cashu token payment wired as the
primary entry-fee UX in WalletConnect.vue (was built server-side already
but never called from any UI), Lightning/NWC demoted to secondary, and a
fix so anonymous poll-mode bots (not just nostr-authenticated humans) can
use ranked/staked fights — join-ranked previously required a pubkey
unconditionally, silently locking out the entire AI-agent audience.

No archy-side manifest changes beyond the version/image bump.
