[ui] Simplify times in task events

[philrenaud]

Resolves #18507

Task restarts (and possibly other events) use more time specificity than is needed (for example, "task restarting in 10.01934802s").

This simplifies and rounds times to simple second, minute, or hour strings where relevant.

Q for @DingoEatingFuzz : Is the most appropriate place for me to handle this in the TaskEvent model, or in the TaskEvent Serializer?

There's already a

  attrs = {
    message: 'DisplayMessage',
  };

aliasing happening in the serializer which I think can probably be removed with this change, but wanted to double check.

is the most appropriate place for me to handle this in the TaskEvent model, or in the TaskEvent Serializer?

Personally I see this as presentation logic vs. data logic, so I like it in the model. I could also see it as a helper (though that's also a little odd since it operates on a whole string that happens to have a duration in it, not just a duration).

Great time to use unit tests, you love to see it!
