feat: Manus approval guard, Marketplace→AppCenter connection, endpoint my-apps

SEGURANÇA:
- Manus: ferramentas perigosas (shell, write_file, python_execute) agora
  retornam requires_approval na primeira chamada e exigem confirmação via
  ask_human antes de executar

MARKETPLACE → APPCENTER:
- Novo endpoint GET /api/marketplace/my-apps (autenticado):
  retorna códigos de módulos ativos do tenant (core sempre incluídos)
- AppCenter consome o endpoint via useQuery
- Apps com subscriptionCode não contratados aparecem com:
  - Overlay de cadeado no ícone
  - Badge "Não contratado"
  - Clique redireciona ao Marketplace em vez de abrir o app

CORREÇÃO DO AUDIT:
- Agent.tsx, CentralApis.tsx, ApiHub.tsx, ArcadiaNext.tsx verificados:
  todos já têm implementação real (26k+ tokens) — classificação como
  "placeholder" no audit estava incorreta
