[Feature Request] Add security audit logging for API endpoint authentication checks

**Bug Description**
I was doing a security audit on my application and it flagged the fable 5 safeguards. I just wanted to make sure my endpoints were properly authenticated and hardened.

**Environment Info**
- Platform: win32
- Terminal: WarpTerminal
- Version: 2.1.252
- Feedback ID: 862061eb-93e2-462a-8bc6-b6893c484054

**Errors**
```json
[]
```

The issue names no files, tests, or entry points, and its body describes an audit concern rather than a concrete change. First clarify the intended authentication checks and audit-log behavior with the issue author; done should be defined by an agreed scope and verifiable tests.
