script crash when I added a lora with lora_path.

Start with examples/wan2.1_fun/predict_v2v_control.py and videox_fun/utils/lora_utils.py, especially merge_lora around lines 399-417. Reproduce the crash with lora_path and the reported WanTransformer3DModel traceback, then compare the loaded layer names with the model attributes. Done means the script merges the LoRA without crashing.
