🛡️ Sentinel: [HIGH] Fix path traversal vulnerability

[mleem97]

🚨 Severity: HIGH
💡 Vulnerability: The SetPortrait method in CustomEmployeeManager constructs a file path using employeeId without validation.
🎯 Impact: Bypassing registration checks via direct calls or deserialization could lead to unauthorized file access outside the sandbox.
🔧 Fix: Added explicit path traversal validation using IndexOfAny and Contains("..") to SetPortrait. Wrapped the file access in a conditional block to ensure fallback logic remains reachable.
✅ Verification: Verified code compilation and test execution.
