Show AssetWatcher/EventTrigger health in the UI #73892

Description

It would be really useful to show infos regarding AssetWatcher/EventTrigger health in the UI.

Use case/motivation

Currently, in order to have a view of the health of an EventTrigger, which run on the triggerer, the only way seems to be looking at the logs of the triggerer service.
As a user, when I am looking at a DAG or at an Asset in the UI, I would like to quickly understand the health of the event based mechanism I setup. Especially, if the EventTrigger encounters an non handled case, by this I mean "throw an unhandled exception", I would like to see some red in the UI and the reason why it is red. Either in the Asset view or in the DAG view, ideally both.

Related issues

This was mentioned to some extent in issue #55317 which was closed as duplicate of #48017. #48017 was closed as completed in #55643.
However #55643 seems to have changed the backend only, no impact on the UI from what I can see.

    Shouldn't it go through an approval process before anyone starts working on it ? Also, I am not sure that I am the one deciding who works on it. Sorry, I am not familiar with the process.

    I think the Triggerer health is shown in the UI? That's where Event Triggers run... I think it would be a pretty major change to try and isolate the logs from each Asset Watcher. BTW, we don't do this for regular triggers today.
