fix(superset): resolver slug → UUID antes de gerar guest token e embeddar

O SDK do Superset exige o UUID do embedded config (não o slug) tanto no
embedDashboard quanto no guest token. Agora o backend resolve:
  slug → dashboard ID → embedded UUID → guest token com UUID
E retorna { token, embeddedId } para o frontend usar no embedDashboard.
