Some cleanups for PidginDisplayItem
Review Request #3177 — Created May 10, 2024 and submitted
Set the title labels to ellipsize at the end, fix the position of the notification indicators, and hide the notification indicators when the item is selected. We're hiding them because a later review request is going to allow us to show additional widgets on hover and selection.
Ran the turtles and opened a bunch of conversations and notifications. See the screen shots in the review.
