* Fix adrenal crisis being incurable (Fixes#77086) (#77117)
## About The Pull Request
Fixes#77086
Adrenal Crisis lacks the CURABLE flag, meaning it will never be cured,
even if the cure is present.
I opted to remove the `var/disease_flags` from it, since it has
`CAN_CARRY|CAN_RESIST`, if I add `CURABLE` to that it's the same flags
as the base `/datum/disease` datum has, and I think it's cleaner to not
list them again if they don't change from the base.
Not sure if it was ever curable? Seemed to have these flags since it was
added. And the `has_cure` proc seemed to check for that flag even back
then.
## Why It's Good For The Game
Disease that's supposed to be curable is now curable.
## Changelog
🆑
fix: Determination can now actually overcome your adrenal glands, making
adrenal crisis a curable condition!
