Guard auto-review when API key secret is unavailable

This workflow is triggered by pull_request, which includes PRs from forks where GitHub does not provide repository secrets; in that context secrets.FACTORY_API_KEY resolves empty, so the Droid step will fail instead of reviewing the PR. If this check is required, external contributor PRs will be blocked by a permanent red run. Add a fork/secret guard (or move to a safe pull_request_target design) so the job skips cleanly when the secret is not available.
