Returns the project-scoped feature flags served by the gateway for the path project, evaluated server-side with the project as the targeting entity, as {"flags": {"": }}. Any caller with a read role on the project may read this. The key set is not a compatibility surface: it changes as flags are added and retired, so treat an absent key as its own default.
