Deploy searxng ai-summary-20260805 (LLM server API key support)

New multi-arch image (amd64+arm64) built from searxng fork ce400f993:
the ai_summary plugin can now authenticate to the LLM server with an
ai_summary.api_key, sent only to the configured base_url.

secret.example.yaml documents the ai_summary block, including the new
optional api_key.
