Populate Model Card and Add Pipeline Tag

This PR populates the automatically generated model card with essential information from the paper and adds the correct `pipeline_tag` and confirms the `library_name`. It also updates the README to include a more descriptive summary and example usage.

+# *Leffa*: Learning Flow Fields in Attention for Controllable Person Image Generation
+This model, presented in [Learning Flow Fields in Attention for Controllable Person Image Generation](https://huggingface.co/papers/2412.08486), is a diffusion-based model for controllable person image generation.  It allows for precise manipulation of both appearance (virtual try-on) and pose (pose transfer) while minimizing distortion of fine-grained details.
+[📚 Paper](https://arxiv.org/abs/2412.08486) - [🤖 Code](https://github.com/franciszzj/Leffa) - [🔥 Demo](https://huggingface.co/spaces/franciszzj/Leffa) - [🤗 Model](https://huggingface.co/franciszzj/Leffa)
+## How to use
+```python
+from diffusers import StableDiffusionPipeline, DPMSolverMultistepScheduler
+pipe = StableDiffusionPipeline.from_pretrained("franciszzj/Leffa", torch_dtype=torch.float16)
+pipe.scheduler = DPMSolverMultistepScheduler.from_config(pipe.scheduler.config)
+pipe = pipe.to("cuda")
+# Example usage for virtual try-on (replace with your image paths)
+image = Image.open("person_image.png")
+prompt = "a person wearing a red dress"
+image = pipe(prompt=prompt, image=image).images[0]
+image.save("output.png")
+```
+##  Further Details
+(The rest of the original README content can be retained here, potentially reorganized for better clarity and flow.  Sections that are currently placeholders should be filled with details from the paper or other relevant sources.)
