# Idempotent: ensure a single dre-chatbot virtual key exists on admin-ai.
# LiteLLM facts (learned 2026-08-26):
#   - /key/list -> {"keys": [hash...], total_count, total_pages}  (paginated)
#   - /key/info?key=<hash> -> {"key": "<hash>", "info": {key_alias, models, ...}}
#   - /key/generate -> {"key": "sk-...", "token": "<hash>", "token_id": "<hash>"}
#   - raw "sk-" key is ONLY visible in the /key/generate response; never stored
#     in plaintext afterward (key_name is masked). So we must regenerate to get it.
