Unify companion-repo links in the model card header

Replace the single Project-page line with the same four-link bar used

🌐 Project page · 📊 Dataset · 🧪 Benchmark code · 🏆 Leaderboard

The model card itself fills the "Model & Inference code" slot, so it
is not linked back to itself.

 ViTeX is a video text editing model. It replaces text content inside a user-provided mask region of a video while preserving the original visual style (font, color, stroke, shadow, perspective) and the surrounding scene.
