Initial AuroraIMG-6M API

An authenticated CPU text-to-image API for direct-img, serving an ONNX
conversion of AuroraAI-Research/AuroraIMG-6M (Apache-2.0). About 0.4s per
image and ~150-200 MB RAM. Output matches the original pipeline to within
1/255 per pixel.

Pushes to main build ghcr.io/direct-img/auroraimg-6m:main and trigger the
Dokploy deploy webhook.
