Increases move resistance on NODE Drones, adds handling for when the drone is seperated from the node (#83309)

## About The Pull Request

NODE Drones now have higher move resistance
(MOVE_FORCE_EXTREMELY_STRONG), preventing them from being bumped off the
node, pulled away, or lifted away by a fulton extraction kit.

As an extra layer of assurance, the NODE Drone will depart from the site
if it is moved off of its vent.

## Why It's Good For The Game

Closes #83164.

I'm pretty sure these things shouldn't really be ever moving off of
their vents.
## Changelog
🆑 Rhials
fix: You can no longer force NODE Drones off of ore vents. That includes
using fulton packs!
fix: When a NODE Drone is forcibly separated from its vent, it will fly
away.
