fix(ci,cloud-frontend): silence biome lint warnings on intentional mount-only useEffect deps

direct-crypto-credit-card.tsx — `useEffect(() => setTokenSymbol(null), [selected?.network])` is intentionally keyed only on the network so we reset the token selection when (and only when) the network switches; biome was flagging it as missing deps. Added biome-ignore with rationale.

Also picks up the parallel-agent landing/hero-section + ConditionalWalletProviders work that was uncommitted in the worktree.
