Krea2ControlNetLoraLoader with an SDXL LLLite/ControlNet file (e.g.
kohya_controllllite_xl_openpose_anime_v2.safetensors) produced a generic
'No block LoRA patches matched' RuntimeError because the file has no
*.lora_A/*.lora_B pairs at all. Add a fast sanity check in the openpose
route that raises an actionable message naming the file type mismatch and
the correct Krea2 openpose LoRA to load.
