Integrate Sentry with the error boundary

[andreaskienle]

Currently, frontend errors are caught at the top level by an error boundary (main.tsx).

We should probably log these errors with Sentry.

There is an error boundary component by Sentry which we could use: https://docs.sentry.io/platforms/javascript/guides/react/features/error-boundary/

Acceptance Crtieria

• End user errors should be sent to Sentry
• In Sentry we can ignore expected End user erros (e.g. broken links)
