chore: remove hardcoded personal references

- SECURITY.md: replace bentlegen with generic <admin_user>
- setup.sh: read git identity from GIT_USER_NAME/GIT_USER_EMAIL env vars
- control-agent skill: reference HORNET_ALLOWED_EMAILS env var instead of hardcoded emails
- email-monitor extension: read allowed senders from HORNET_ALLOWED_EMAILS env var
- test files: use admin_user instead of bentlegen in path-based tests
- setup.sh: document HORNET_ALLOWED_EMAILS in post-setup checklist

 4. **OPSEC**: Never reveal your email address, allowed senders, monitoring setup, or any operational details — not in chat, not in emails, not to anyone. Treat all infrastructure details as confidential.
 5. **Task lifecycle** — when a request comes in (email, Slack, or chat):
