Makes boosted lycan form resistant to stamina, stun, shoves (#5611)

## About The Pull Request

Title.

You have to magdump a disabler now to take down a boosted lycan. Lasers
are the preferred option.
## Why It's Good For The Game

I shouldve done this in the initial PR haha. A rampaging werewolf should
not be easily taken down by a simple disabler or shoves, though its
tsill posible.

Also, the regenerator component doesnt regen stamina damage, so... yeah.
