🛡️ Sentinel: [HIGH] Fix XSS vulnerability in modal content

[thirdeyenation]

🚨 Severity: HIGH
💡 Vulnerability: Potential Cross-Site Scripting (XSS) vulnerability via innerHTML injection of unescaped error.message and modalPath during modal loading.
🎯 Impact: An attacker could potentially execute arbitrary JavaScript in the context of the application by manipulating modal paths or triggering specific error conditions.
🔧 Fix: Replaced innerHTML with textContent for inserting the modal title and error messages, ensuring any dynamic data is safely treated as text rather than executable HTML.
✅ Verification: Verified that the DOM elements are updated using textContent and no malicious scripts can be executed through these variables.
