fix: address review feedback — tokens, secrets, no hardcoded IPs

- Fix token_secret for gpt41/gpt5-mini/gpt41-mini: use GPT_REVIEW_TOKEN
  instead of SONNET_REVIEW_TOKEN (wrong reviewer identity)
- Move LLM base URL back to secrets.LLM_BASE_URL (prevents exfiltration
  via PR-controlled matrix values)
- Remove hardcoded internal IP from workflow file; only provider path
  suffix (/anthropic/v1, /openai/v1) remains in matrix

Addresses: security-review-bot REQUEST_CHANGES (major: exfiltration risk,
minor: HTTP/hardcoded IP) and sonnet-review-bot REQUEST_CHANGES (major:
wrong token_secret on gpt entries).
