[MIRROR] Security photobooths have their own ID (#1963)

* Security photobooths have their own ID (#82628)

## About The Pull Request

Prevents the HoP's photobooth button from connecting to the security
photobooth via having the same ID.

## Why It's Good For The Game

I forgot to add this when I made the security photobooth but it's
important that by default without any varedits, the HoP and security
photobooths stay separate.

## Changelog

:cl:
fix: The HoP's photobooth button is now consistently connected to the
HoP's photobooth.
