Improve model card: pipeline tag, paper link, and usage example

This PR enhances the model card for UrbanFusion by:

- Updating the `pipeline_tag` from `any-to-any` to `feature-extraction`. This more accurately reflects the model's function of generating spatial representations and improves its discoverability on the Hub.
- Adding an explicit link to the paper, [UrbanFusion: Stochastic Multimodal Fusion for Contrastive Learning of Robust Spatial Representations](https://huggingface.co/papers/2510.13774), in the introductory description.
- Including a "Minimal Usage Example" section with a Python code snippet, directly sourced from the GitHub repository, to help users quickly get started with generating location embeddings.
- Updating the BibTeX citation to include the correct arXiv ID and URL for the paper.

+## Minimal Usage Example 
+Using pretrained models for location encoding is straightforward. The example below demonstrates how to load the model and generate representations based solely on geographic coordinates (latitude and longitude), without requiring any additional input modalities.
+```python
+import torch
+from huggingface_hub import hf_hub_download
+from srl.multi_modal_encoder.load import get_urbanfusion
+
+device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
+
+# Coordinates: batch of 32 (lat, lon) pairs
+coords = torch.randn(32, 2).to(device)
+
+# Placeholders for other modalities (SV, RS, OSM, POI)
+placeholder = torch.empty(32).to(device)
+inputs = [coords, placeholder, placeholder, placeholder, placeholder]
+
+# Mask all but coordinates (indices: 0=coords, 1=SV, 2=RS, 3=OSM, 4=POI)
+mask_indices = [1, 2, 3, 4]
+
+# Load pretrained UrbanFusion model
+ckpt = hf_hub_download("DominikM198/UrbanFusion", "UrbanFusion/UrbanFusion.ckpt")
+model = get_urbanfusion(ckpt, device=device).eval()
+
+# Encode inputs (output shape: [32, 768])
+with torch.no_grad():
+    embeddings = model(inputs, mask_indices=mask_indices, return_representations=True).cpu()
+```
