Stops borgs from exploding before emag ends (#91821)

## About The Pull Request
Extends the hardstun duration to stop borgs from being able to act
before new laws show up.
## Why It's Good For The Game
Since silicon.log shows that borg gets emagged exactly when they get
clicked by emag, but from POV of the borg emag takes around 8 seconds,
there was a window where emagged cyborg being emagged again could blow
themselves up. Prolonging the hardstun stops that.
## Changelog
🆑
fix: Emag stun is long enough to not let a cyborg act before they see
their new laws
