Hides two do_afters which should be invisible (#89460)

## About The Pull Request and also Why It's Good For The Game

Lately I noticed that watchers display the do_after "working" cog while
channeling their "look away" ability, which looks silly because it
already has its own indicator. That should be hidden.

Actually now I look at this gif again the offset on the cog is fucked
up, probably need to update that for larger-than-usual mobs...

While I was at it I also added "hidden" to mob basic attack forecasts. I
can't think it's _likely_ that anyone will add a mob with a > 1 second
forecast (they are only displayed if the length is at least one second)
but it's not totally impossible.

## Changelog

their gaze attack.
