🛡️ Sentinel: [CRITICAL] Fix Path Traversal in CustomEmployeeManager.SetPortrait

[mleem97]

🚨 Severity: CRITICAL
💡 Vulnerability: The SetPortrait method in CustomEmployeeManager uses the employeeId parameter directly to construct file paths via Path.Combine without sufficient validation. This enables a path traversal vulnerability (CWE-22) when loading images.
🎯 Impact: Direct invocations or deserialization bypasses could pass malicious strings like ../../Windows/System32/... as the employeeId, allowing arbitrary local files to be read and potentially executed or exposed, depending on how the image parsing handles invalid data.
🔧 Fix: Added a defense-in-depth security check that validates employeeId does not contain any invalid characters (Path.GetInvalidFileNameChars()) or .. before attempting to resolve and read the file path.
✅ Verification: Run dotnet test to confirm standard loading still functions without regressions.
