[BUG]: Windows folder paths with backslashes crash YAML config parsing

### Bug Description

## Description

On Windows computers, folder paths use backslashes (for example: C:\Users\username\...).
In multiple test files, temporary folder paths are written into config YAML files inside double quotes:
The YAML config reader gets confused by \U inside double quotes because it thinks \U is a special code rather than a normal folder path.

- 8 unit tests in test_audit_export.py and test_identity_linking.py fail immediately on Windows.
- Any Windows user who writes double-quoted file paths in their config.yaml will see the bot crash on startup with a YAML parse error.

### Steps to Reproduce

1. On a Windows machine, open a terminal in the project directory.
2. Run pytest tests/test_audit_export.py.
3. The tests will fail with a yaml.scanner.ScannerError and SystemExit: 1.
