fix(wanvideo): resolve lora path resolution and name truncation for extra folder paths

- Use get_lora_info_absolute to obtain correct absolute paths for loras
  in LM extra folder paths, instead of folder_paths.get_full_path which
  only searches ComfyUI's standard loras directories (returned None)
- Fix name field truncation: str.split('.')[0] stopped at the first dot,
  replaced with os.path.splitext to only strip the file extension
- Add _relpath_within_loras helper to preserve subdirectory info in the
  name field, matching WanVideoWrapper's os.path.splitext(lora)[0] format
