🛡️ Sentinel: [CRITICAL] Fix Path Traversal

[mleem97]

🚨 Severity: CRITICAL
💡 Vulnerability: SetPortrait inside CustomEmployeeManager is vulnerable to path traversal (CWE-22) due to concatenating employeeId without sanitization.
🎯 Impact: Allows arbitrary file read by an attacker who bypasses the Register validation (e.g. direct calls or deserialization bypasses), leading to potential information disclosure or arbitrary file access.
🔧 Fix: Wrapped the file loading loop in a conditional block to validate employeeId using IndexOfAny(Path.GetInvalidFileNameChars()) < 0 && !Contains(".."), maintaining the fallback logic. Added // [Security] Prevent path traversal in employeeId to protect against direct calls bypassing Register validation comment.
✅ Verification: Ran dotnet test to verify changes did not break anything and successfully compiled.
