[MIRROR] Fixes Epinephrine Healing [MDB IGNORE] (#23866)

* Fixes Epinephrine Healing (#78479)

## About The Pull Request

As described in #78474, epinephrine wasn't properly updating health when
it healed people in crit. This meant that people stayed in crit despite
not being damaged enough to reach the crit threshold (at least until
something else updated their health). This fixes that. Closes #78474.
## Why It's Good For The Game

Epinephrine should actually get people out of crit.
## Changelog
🆑
fix: Epinephrine will now update health properly.
