refactor(app-shell, app-shell-odd): reduce port block analytics reporting frequency

[mjhuff]

Closes RQA-2385

Overview

Instead of reporting every port block event that can happen in an app session (which can be excessive), let's just report one event per session.

Test Plan

• Verified on my Mixpanel acct that port block events aren't excessive.

Review requests

• Just verify the logic is sound. I think reporting this event once per app session is fine. At the end of the day, we just want to use this number to gauge the # of users who experience port blocking issues. We can filter by robot, ID, etc. in Mixpanel to fine tune the results. Let's just cut down on the overall chatter here.
