fix(engine-room): usa valores do preset ENGINES em vez de hardcoded

- Corrige MetaSet: usa type, displayName, category, description do preset
- Corrige Plus: usa valores do preset em vez de hardcoded
- Remove 'java' hardcoded que sobrescrevia o preset correto

Isso garante que as correções feitas no preset ENGINES
(type: python, porta: 8100) sejam refletidas na API.
