## About The Pull Request
https://github.com/tgstation/tgstation/pull/90588 - but for martial
arts. Currently only 3 martial arts has a combo system, yet every single
hud for every living & human has an invisible martial art hud on them
24/7, "just in case".
The HUD in question

## Why It's Good For The Game
Removes having a HUD on every player 24/7 when in most cases it'll never
be used, and removes an unnecessary var on the base hud datum.
## Changelog
Nothing player-facing.
