Fix dynamic duration function signature for ZeroGPU compatibility

- Change get_dynamic_duration to accept *args, **kwargs
- Extract only needed parameters (pipeline, image_size, enable_animation, enable_upscale)
- Fixes TypeError: got multiple values for argument 'pipeline'
- ZeroGPU decorator passes all function arguments to duration function
