[Qwen-image-edit] Batch Inference Issue / Feature Request

### Describe the bug

I am trying to run the batch inference for 'Qwen-Image-Edit-2509', but it will raise inference error

```
AttributeError Traceback (most recent call last)
.venv/lib/python3.10/site-packages/diffusers/pipelines/qwenimage/pipeline_qwenimage_edit_plus.py:633) height = height or calculated_height

AttributeError: 'tuple' object has no attribute 'size'
```

### Reproduction

```
import os
import torch
from PIL import Image
from diffusers import QwenImageEditPlusPipeline
from diffusers.utils import load_image

pipeline = QwenImageEditPlusPipeline.from_pretrained("Qwen/Qwen-Image-Edit-2509", torch_dtype=torch.bfloat16)
print("pipeline loaded")

pipeline.to('cuda')
pipeline.set_progress_bar_config(disable=None)
image1 = load_image("https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/inpaint.png"),
image2 = load_image("https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/cat.png"),
prompts = [
"cinematic photo of a beautiful sunset over mountains, 35mm photograph, film, professional, 4k, highly detailed",
"cinematic film still of a cat basking in the sun on a roof in Turkey, highly detailed, high budget hollywood movie, cinemascope, moody, epic, gorgeous, film grain",
]

with torch.inference_mode():
output = pipeline(
image=[image1, image2],
prompt=prompts,
generator=[torch.manual_seed(0), torch.manual_seed(0)],
true_cfg_scale=4.0,
negative_prompt=" ",
num_inference_steps=40,
guidance_scale=1.0,
)
output_image = output.images
```

### Who can help?

@naykun

Start with the reproduction and inspect diffusers/pipelines/qwenimage/pipeline_qwenimage_edit_plus.py around line 633, where the traceback occurs. Check how QwenImageEditPlusPipeline handles the batched image and prompt inputs, then run the provided example to determine whether the reported batch behavior is supported and what test should capture the expected result.
