feat(compose): add AMD-optimized ComfyUI service

Add a new ComfyUI service to the Docker Compose configuration, specifically tailored for AMD GPUs using ROCm.

- Uses the rocm/pytorch base image for hardware acceleration
- Includes an initialization script to clone and install ComfyUI on first boot
- Configures necessary hardware device mappings (/dev/dri, /dev/kfd) and environment variables for AMD compatibility
- Sets up persistent storage and network integration with the existing proxy and AI internal networks
