🛡️ Sentinel: [HIGH] Fix XSS vulnerability

[thirdeyenation]

🚨 Severity: HIGH
💡 Vulnerability: The showConfirmDialog function dynamically constructs UI elements using innerHTML and unsanitized string interpolation for variables like title, message, confirmText, and cancelText.
🎯 Impact: Attackers or malicious input strings could exploit this to perform Cross-Site Scripting (XSS), compromising user sessions or hijacking the client execution context when the dialog is triggered.
🔧 Fix: Updated the implementation to render the skeleton HTML without embedded variables, select the generated DOM nodes, and populate the dynamic values securely using the textContent property instead.
✅ Verification: Verified manually that the innerHTML string interpolation has been replaced with textContent assignments in the final JS bundle by executing static analysis.
