Various Surgery & Medical fixes, QoL, and adjustments (#18718)

* bunch of medical adjustments

* or so i thought

* De-death surgery

* Update carbon.dm

* Update mob_grab_specials.dm

* yeh

* Palpation

* internal bleeding

* Update life.dm

* duration increase

* adjust these

* Fixes a bug with defibs that I caused

When I reworked get_crit_point, it caused defibs to DEAL oxyloss instead of HEALING it, like it has been doing for the past 8 years. This fixes it.

* fixcees this

* fixes syringe stabbing

* Converts these to managed global lists

* gets rid of disabilities

* Change injury check to use do_after with delay

* lungfix

* actually remove the necrosis

* Fixes brain surgery

* fix language bug

* Update brain.dm

* ghetto surgery adjustments

Buffs some ghetto surgery
Makes some injuries sustained less gnarly if you fail with a ghetto tool.
Some mild typo fixes.
