ComfyUI: GPU (gfx1151 ROCm) build via container

Replace the CPU stock image with a container built from
Containerfile.comfyui on AMD's gfx1151-tagged vLLM base — the only torch
build verified to report torch.cuda.is_available()=True on the Strix Halo
APU (Radeon 8060S, capability (11,5)).

- Containerfile bakes the ComfyUI code in and installs its deps, but skips
  the torch family (the base image already ships the gfx1151 ROCm
  torch/torchvision/torchaudio; an unpinned 'torch' in requirements.txt would
  clobber the gfx1151 kernels).
- compose comfyui service: build + image comfyui-rocm:gfx1151, passes
  /dev/kfd + /dev/dri, adds video+render groups, drops --cpu. Models/data
  persist under /opt/comfyui.
- Un-skip the four compose-wiring acceptance tests (the gate for this work).
