Research and integrate unified (full-stack) logging service

[kyanmichael]

For debugging purposes, it'd be very helpful to use a full-stack logging service, where errors, warnings and debugging log messages and data can be logged on the frontend and backend, and then merged and displayed in a unified log. Possible services to research: Rollbar (I've used this a lot in previous projects), Datadog, Sentry, Bugsnag, Raygun, LogRocket, etc.
