"""
Order detail dialog.

Mainly a debugging aid: shows exactly what JIRA sent back for this
ticket (raw payload), plus the tracking numbers ShipStation supplied
and the JIRA status they suggest - handy for the end-of-day close-out
without having to piece it together by hand. Also offers quick jumps
out to JIRA and Google Maps, since those are common next steps when
something about a ticket needs a closer look.
