Hetzner: Free experimental OpenAI-compatible inference

Hetzner's no-cost experimental OpenAI-compatible inference API now documents Qwen3.8-27B alongside Qwen/Qwen3.6-35B-A3B-FP8. This is a meaningful model-catalog expansion to the already-known Hetzner experiment; availability is not guaranteed and the service should not be used for production.
