[MetaStation] Chefs can now toggle the counter shutters (tgstation#75342

)

## About The Pull Request
Title.

## Why It's Good For The Game
Between tgstation#74653 and tgstation#75098 (not sure who did it) there was just a generic
EAST button near the food processor, and the shutters couldn't be closed
presumably (the ones on the counter). Accidents happen!

Saw this downstream while I was remapping something.

## Changelog

:cl: Jolly
fix: [MetaStation] Chefs may now brutally murder- I mean deny service to
the station patrons once again, the shutters over the counter may now be
closed once again.
