Fixes SSWardrobe stealing a camera from the camera app when on a dummy, causing a harddel (#87903)

## About The Pull Request

See name, if a dummy somehow gets hold of a PDA with the camera app
installed (This just so happens to be a default PDA program in the case
on Nova, Skyrat, and Bubber), and the delete_equipment proc is called,
the camera inside the PDA gets sent to the wardrobe because of
`/datum/outfit/job/assistant/gimmick/hall_monitor` having one, and then
qdelled with the PDA, leaving a hanging ref

This causes a harddel during tests that has caused me great pains to
locate. Turns out a single example holodisk with the clown holds a
magical key to trigger all this: a single PDA

## Why It's Good For The Game

Fixes a harddel. There might be other similar ones hiding in the dark
like cameras in other objects.
