<!-- start pr-codex -->

---

## PR-Codex overview
This PR focuses on enhancing the `authorizeNode` function by improving type handling for request headers and refactoring how headers are accessed. It introduces a type guard for distinguishing between header types and updates the way headers are retrieved in various functions.

### Detailed summary
- Updated `req` type in `AuthInput` to allow `Request`.
- Added `isNodeHeaders` function to differentiate between `IncomingHttpHeaders` and `Headers`.
- Refactored `getHeader` function to use `isNodeHeaders` for retrieving headers.
- Modified `extractAuthorizationData` to use `getHeader` for constructing the URL.
- Updated `logHttpRequest` to use `getHeader` for SDK-related headers.
