fix(home): esconde "Powered by Morpheus" até a subnet bater 100k MOR (#232)

A faixa "community × community / Back Gnars" aparecia na home desde já,
adiantando (spoiler) o reveal que só deve rolar quando a subnet atingir a
meta (SUBNET_GOAL_MOR = 100k). Agora o componente é async e lê o total
stakeado on-chain (subnetsData(id).deposited, igual ao hook useGnarsSubnet);
renderiza null abaixo da meta. Fail-closed: se a leitura on-chain falhar,
esconde em vez de revelar. Envolto em <Suspense fallback={null}> pra não
bloquear o shell da home (que é ISR, revalidate=300).
