[mox56]

Description

This pull request improves the application error handling by introducing a React Error Boundary and providing a user friendly error state when profile data fails to load.

Related Issues

Closes issue#1266

Changes Proposed

• Added an ErrorBoundary component using getDerivedStateFromError.
• Wrapped the application with the new error boundary in pages/_app.js.
• Updated ErrorPage to support reusable error messages and an optional Retry button.
• Improved data fetching by displaying a visible error state instead of silently returning an empty array when requests fail.
• Added a Retry button that allows users to retry loading profile data after a failed request.
