fix(engine-room): URLs corretas para health check de containers externos

- Adiciona getEngineHealthUrl() para resolver URLs dinamicamente
- MetaSet (Superset) usa SUPERSET_HOST ou 'superset' por padrão
- Plus usa PLUS_HOST ou 'localhost' por padrão
- Resolve problema de localhost:8088 falhar para Superset
