John Willard 06ca7a4481 Hud screens now set hud owner in Initialize. (#76772)
## About The Pull Request

Adds an arg in huds' screens to add the hud owner in the Initialize,
instead of manually setting it every time we need to.
This is already done in ``New()`` for lobby screens, which I left intact
as lobby screens are used for new players, and are given out before
atoms are Initialized. Everything else, however, uses Initialize, so it
does not mess with any other args in their own Initializes (like the
Escape menu).
This also allows us to set the screens' HUDs as a private var, to ensure
this won't be messed with in the future.
Lastly I replaced instances of ``client`` with ``cannon_client`` to be
consistent with a lot of other parts of hud code.

## Why It's Good For The Game

Huds are easy to break when they do not have a hud owner, and for
something as important as that I believe it should be something you
opt-out of when you don't want it, rather than something you opt-into by
manually setting hud owner every time.
This cuts down on a lot of copy paste in hud code for humans, aliens,
etc.
