[MIRROR] Prosthesis organ manipulation no longer makes you harm target when you use incorrect tool [MDB IGNORE] (#20043)

* Prosthesis organ manipulation no longer makes you harm target when you use incorrect tool (#74184)

## About The Pull Request

currently if someone is in surgery you can only harm them with a
surgical tool if you are in combat mode
the way the check works is that it only applies to tools that have the
SURGICAL_TOOL item flag

prosthesis organ manipulation is the only surgery that uses normal
engineering tools, and because it involves steps with normal tools, it
means that if you forget or misclick you can easily hurt someone with
the wrong tool

this makes that not happen anymore

## Why It's Good For The Game

i feel like it makes sense for the surgery that uses engineering tools
as surgery tools to treat engineering tools as them, with the same
considerations with regards to only having you bludgeon the patient if
you wanted to

## Changelog

incorrect engineering tool
