feat: handle Docker Bearer token auth for upstream registries (#60)

Docker Hub (and other registries) return 401 with a `Www-Authenticate: Bearer realm=...` challenge even for public images. The proxy now:

1. Detects 401 + Bearer challenge
2. Parses realm/service/scope from the header
3. Fetches an anonymous token (or authenticated if username/password configured)
4. Retries the original request with the Bearer token

Fixes: `docker pull artifactapi.../dockerhub/library/redis:latest` returning "unauthorized: upstream returned 401"
