Subject: [PATCH] fix: add UpscaleModelLoader and correct widget order in
 UltimateSDUpscale workflow

- Added UpscaleModelLoader node (node 8) for RealESRGAN model
- Connected upscale_model input to UltimateSDUpscale
- Fixed widgets_values array to match correct parameter order:
  upscale_by, seed, steps, cfg, sampler_name, scheduler, denoise,
  mode_type, tile_width, tile_height, mask_blur, tile_padding,
  seam_fix_mode, seam_fix_denoise, seam_fix_width, seam_fix_mask_blur,
  seam_fix_padding, force_uniform_tiles, tiled_decode
- Updated version to 1.1.0
