    Generate an audio file (MP3) using the Pollinations text-to-speech API.
    
    The prompt is appended with a system message explaining that this is Eve,
    a WhatsApp bot that can generate images from Flux and help users generate images.
    To generate an image, the user should send a message like: /imagine {prompt}

    Parameters:
        prompt (str): The text prompt for audio generation.
        model (str): Model identifier (default: openai-audio).
        voice (str): Voice parameter (default: coral).
        audio_dir (str): Directory where the audio file will be saved.

    Returns:
        tuple: (audio_file_path (str), audio_data (bytes)) or None if failed.
