kinesis changes + smaller misc modsuit stuff (#77241)

## About The Pull Request
renames plasmaman helmet exempt flag to stackable helmet exempt. hat
stabilizer now cares about this instead of letting you stack eva helmets
on top of modsuit helmets
improves some code that dripped in quality when i was on break
kinesis has some tweaks
previously it used to stun for a set amount of time - i think this is
because the creator couldnt figure out how to stop movement while being
held? this is changed, now as long as youre holding someone they are
immobilized
you can cancel your kinesis without throwing or moving out of range by
using right click on the click catcher
adds an admin version of kinesis just for the admin suit. it can grab
(almost) ANYTHING and config menu lets you enable phasing, which makes
it so the atom you grabbed phases through everything. pick up that can.

## Why It's Good For The Game
its fun

## Changelog
🆑
balance: hat stabilizer module can now hold what plasmaman helmets can
hold
qol: kinesis module can be stopped without launching an object with
right click
balance: kinesis module stuns last until the kinesis stops
add: admin suit has a version of kinesis that can pick up anything at
any range and can be configured to make grabbed mobs phase through walls
:)
