feat(gpu): add GPU support for comfyui, photoprism, libretranslate

Added var_gpu=yes to ct scripts:
- comfyui.sh - Stable Diffusion (CRITICAL: had GPU selection but no passthrough!)
- photoprism.sh - TensorFlow face detection + FFmpeg transcoding
- libretranslate.sh - PyTorch ML translation

Added setup_hwaccel to install scripts:
- comfyui-install.sh
- photoprism-install.sh
- libretranslate-install.sh

These apps use PyTorch/TensorFlow for ML and benefit significantly
from GPU acceleration (Intel XPU, AMD ROCm, NVIDIA CUDA).
