Shitmed Update 2 - [Insert Snarky Remark] (#1271)

# Description

![image](https://github.com/user-attachments/assets/b10f1e33-94fb-4ded-a644-b9945b58dbc5)

Honey wake up, another shitmed PR with 5 features and a trillion bugs! I
love bloat.

---

# Known Bugs
- A lot of shit with changelings lol
- Markings suddenly disappear from your entity apparently at random.
Wizden exclusive issue as of now.
- Fire heretics explode when ascending due to part damage shitcode
(sorry)
- Some exceptions/null point references at round end, tentatively
related to salvage corpses.
- Slots having wonky behavior due to not being networked. More of a
broad issue with how I implemented them initially.
- Arachne are FUCKED with surgery, I was incredibly tempted to set them
to roundstart: false, but I'll try to hotfix it this week.

---

# Changelog

:cl: Mocho, Deltanedas
- add: Ported Ghetto Surgery from Deltanedas!
- add: Ported fishops organs from Deltanedas!
- add: Added different step durations to each surgery step.
- add: Added a T2 research for advanced surgical tools
- add: Added a T3 research for an omnitool for surgery.
- add: Added Surgical and Advanced Surgical modules for Mediborgs
- add: Mediborgs can now perform surgery!
- add: Added lobotomies as an operation. Godspeed you psychopaths.
- add: Added cybernetic arms, legs and eyes.
- add: Added EMP weaknesses to all cybernetic parts (the day of
reckoning will come for IPCs soon)
- add: Losing your eyes now blinds you.
- fix: Fixed a few species that did not inherit from BasePart's, thus
taking damage types they shouldn't on their limbs.
- fix: Fixed harpy lungs not being usable in surgeries.
- fix: Fixed biosynthetic and other printable parts not allowing you to
attach body parts to them.
- fix: Fixed fire being able to destroy your chest.
- fix: Fixed entities being able to take over your body by just
inserting a brain or another head on top of you.
- fix: Fixed some shitcode that didnt let rejuvenate or godmode work
properly.
- fix: Fixed bionic arm, and cybernetic eyes traits not working properly
due to shitty networking.
- tweak: Increased tend wounds's speed by double, and bumped up the
values on its calculations. DEATH TO TOPICALS, LEAVE THOSE TO TIDERS.
- tweak: Beheading an entity now doesnt let it move, speak, and forces
it to the ground immediately (literally 1984!!11!!)
- tweak: Changed sprites on most surgical tools to now use /tg/ sprites.
- tweak: Unbound shitmed targeting doll keybinds by default (did you
know we have those).
