Add client error endpoint to backend

[Isti01]

The goal is to make it easier to detect errors on the frontend and have enough data to investigate the issue

Some fields to send that are going to be useful:

• Error stacktrace: error.stack available when error is an Error object
• Browser: navigator.userAgent
• Current page: window.location.href
• User role if available: useAuthContext().authInfo?.role

Where to detect errors?

• Put a script tag in the head of the document and subscribe to window.onerror more on this here. The backend url can be interpolated into the script at build by Vite
• Add error reporting to the ErrorBoundary component
