chess c8ddb210d2 Improve codex doctor network diagnostics (#38918) ...

## What changed

- Probe the configured Responses inference endpoint with Codex's route-aware HTTP client, including configured proxy and custom CA behavior.
- Classify TLS, proxy authentication, proxy configuration, resolution, and timeout failures into actionable diagnostics.
- Report privacy-safe macOS system proxy state and suggest enabling `respect_system_proxy` when a configured proxy is otherwise unused.
- Preserve system-root fallback when a custom CA is invalid, and account for provider-specific API key configuration when selecting the probe route.

## Testing

- Cover inference endpoint selection, invalid custom CA fallback, proxy authentication failures, TLS classification, and macOS proxy reporting.
