fix(gallery): remove broken DeepSeek V4 0731 entry (#11313)

fix(gallery): repair DeepSeek V4 0731 entry

Use the official single-file ggml-org MXFP4 artifact with its verified SHA256 and route it through llama.cpp instead of treating an unsloth repository page as a ds4 model file.

   description: "# DeepSeek-V4-Flash-0731\n\nTechnical Report\U0001F441️\n\n## Introduction\n\n**DeepSeek-V4-Flash-0731** is the official release of **DeepSeek-V4-Flash**, superseding the preview version, with substantially enhanced agentic capabilities. It has the same model structure as DeepSeek-V4-Flash-DSpark, i.e. it comes with a speculative decoding module attached.\n\nDeepSeek-V4-Flash-0731 outperforms DeepSeek-V4-Pro (Preview) on benchmarks listed below despite its far smaller activated parameter count, and is broadly competitive with the strongest proprietary models available.\n\nNotes:\n\n1. For the Code Agent tasks among the public benchmarks above, DeepSeek-V4-Flash-0731 is evaluated with the minimal mode of DeepSeek Harness (to be released) as the agent framework, using the `max` reasoning effort level with `temperature = 1.0, top_p = 0.95`.\n2. † DSBench-FullStack is an internal full-stack development test set; DSBench-Hard is an internal test set of difficult coding-agent problems.\n\n## Chat Template\n\n...\n"
