chore: Ensure we use structured logging when returning disruption commands

[jonathan-innis]

Fixes #N/A

Description

This change moves all of the structured data that was previously in the disruption message into actual structured fields. This should make it easier to parse data when using logging solutions that automatically parse-out JSON keys

Before Change
