🛡️ Sentinel: [CRITICAL] Fix Path Traversal in SetPortrait

[mleem97]

• 🚨 Severity: CRITICAL
• 💡 Vulnerability: CustomEmployeeManager.SetPortrait uses unvalidated employeeId to dynamically construct paths via Path.Combine, leading to potential directory traversal (CWE-22) and arbitrary file read bypasses if called directly.
• 🎯 Impact: Malicious mod identifiers could read sensitive system files or traverse outside the intended ModAssets directory, compromising system confidentiality.
• 🔧 Fix: Added independent validation (IndexOfAny(Path.GetInvalidFileNameChars()) >= 0 || Contains("..")) in SetPortrait before concatenating the image paths.
• ✅ Verification: Ensured the code successfully compiles and unit tests pass.
