Upgrade ollama from 0.9.3 (IPEX-LLM) to 0.15.6 (official) with Vulkan Intel GPU

Replace the IPEX-LLM portable zip (bundling a patched ollama 0.9.3 with SYCL)
with the official ollama 0.15.6 release using the Vulkan backend for Intel GPU
acceleration. The official ollama project does not ship a SYCL backend; Vulkan
is their supported path for Intel GPUs.

- Use official ollama binary with Vulkan runner (OLLAMA_VULKAN=1)
- Strip CUDA/MLX runners from image to save space
- Add mesa-vulkan-drivers for Intel ANV Vulkan ICD
- Remove all IPEX-LLM env vars and wrapper scripts
- Simplify entrypoint to /usr/bin/ollama serve directly
- Clean up docker-compose.yml: remove IPEX build args and env vars

Tested: Intel Arc Graphics (MTL) detected, 17/17 layers offloaded to Vulkan0
