Deploy now also passes OPENAI_API_KEY (the 3rd of OPENAI_BASE_URL/MODEL_NAME/
OPENAI_API_KEY AM expects). HM mints a hidden, unlimited-quota sk- token for the
user per agent ("sk-"+key, billed to the user), injects it as OPENAI_API_KEY, and
stores the token id on the deployment. The token is revoked on delete and rolled
back if AM start / persist fails (no leaked keys). gateway accepts Bearer
sk-<key> (middleware strips sk-).
