chore(gallery): serve ternary-bonsai-2-27b with the bonsai backend

PTQ1_0 is a Prism-private GGUF type (GGML_TYPE_PTQ1_0 = 143 in the
PrismML llama.cpp fork), so stock llama-cpp cannot load it. Switch to
the bonsai backend like the existing ternary-bonsai-27b entries, and
replace the scraped Qwen3.8 description and icon.

-    > For users seeking managed, scalable inference without infrastructure maintenance, the official Qwen API service is provided by Qwen Cloud.
-    > In particular, **Qwen3.8-27B** will be available as a hosted version with more production features, e.g., 1M context length by default, official built-in tools. For more information, please refer to the Qwen3.8-27B Overview. The service is coming soon. Stay tuned for updates.

-    Following the widespread community adoption of the Qwen3.5 and Qwen3.6 series, we are pleased to introduce Qwen3.8, the most capable generation in the Qwen open-model family to date.

+    Ternary Bonsai 2 27B (PrismML) is a 27B-class reasoning model with ternary
+    transformer weights. This PTQ1_0 build packs the trits densely at 1.75 bits
+    per weight (5.95 GB) and includes the Q8_0 vision projector. PTQ1_0 is a
+    Prism-private GGUF type, so the entry uses the bonsai backend (PrismML's
+    llama.cpp fork) instead of stock llama.cpp.
