Holobarrier toggle removal (#79293)

## About The Pull Request
this PR removes the PENLITE holobarrier’s biometric scanner toggle
function activated by hitting the holobarrier.

## Why It's Good For The Game
This is good for the game as having the toggle is quite useless because
the only reason someone would have it up is to keep sick people out.

There is no point to turning off the biometric scanning because you may
as well have nothing put up in the first place.

This also prevents people from unknowingly turning it off allowing sick
patients to infect valuable medical staff.
