Search error by client error UUID

[Jellyfrog]

We can get the assigned UUID with \Facade\Ignition\Facades\Flare::sentReports()->latestUuid() but you can't search for it,
Making it really hard to help a customer saying "I got this error code"

We've recently added this. You can now filter errors and occurrences using the tracking_uuid filter: https://flareapp.io/docs/flare/general/searching-errors
