We want to add Sentry in our frontend. We want to follow this procedure.

Important

1. This can't be merged until we have a privacy policy in place
2. We won't capture any personal data, we need to remove any personal data (as IP address) using a before event
3. When the UI starts, users will be asked if they want to opt in or opt out crash reports. They can change this option in the settings anytime. We don't have designs for this but not sure if we need any for the popup
4. The actual sentry DSN has to be injected in build time to avoid it being leaked to the repository (in docker build time, I'd say)
