Allow Admins to Recategorize User-Reported Emails in the Queue

When reviewing user-reported emails in the queue, we currently have no way to change the category assigned to a report. For example, if a user submits a report as spam, but upon review I determine it is actually a phish (or vice versa), I have no ability to correct that classification before taking action.

The Ask: Add the ability for admins/reviewers to manually recategorize a reported email directly from the queue view — for example, changing a report from "Spam" to "Phish" (or any other available category) prior to or during remediation.
