// newEFCEngineREP creates and initializes an EFCEngine instance for testing purposes.
//
// This function builds a runtime info object based on the given name and namespace,
// then constructs an EFCEngine with a fake Kubernetes client, empty runtime object,
// and a null logger. It also initializes the Helper utility for the engine.
//
// It is mainly used in unit tests (e.g., TestSyncReplicas) to simulate
// EFCEngine behavior without interacting with a real Kubernetes cluster.
//
// Parameters:
// client - a Kubernetes client (usually a fake client for testing)
// name - the name of the EFCRuntime
// namespace - the namespace of the EFCRuntime
//
// Returns:
// *EFCEngine - a fully initialized EFCEngine instance for testing
