initial commit: FastAPI translator proxying to Ollama on radagast

- app.py: /api/models filtered to gemma+aya, /api/translate streams
  NDJSON from Ollama with stream:true, /healthz for k8s probes
- static/index.html: dark-mode UI, three dropdowns (source/target/model),
  live token streaming with spinner+pulse+timer indicators
- Dockerfile: two-stage uv build, slim Python 3.13 runtime
- .gitea/workflows/build.yml: multi-arch (amd64+arm64) build, push to
  Scaleway registry on push to main
- build.sh: manual fallback if Gitea Actions isn't available
