Buffs the SC/FISHER Saboteur Handgun. (#81553)

## About The Pull Request
The saboteur gun will now silence pAIs, toggle off radio broadcasting
(won't auto-relay nearby speech), disable turrets, chill out secbots a
little, and turn off APCs like power outages do.
The disrupt duration has also been buffed from 10/20 to 15/25 for ranged
and point-blank respectively.
Removed a conspicious chat message from an otherwise inconspicious gun.
Brought the code up to date.

## Why It's Good For The Game
The concept is cool, alas it's also undermined by how much of a joke
it's right now, and the game has plenty already.
The amount of interactions it has with things is underwhelming, so you
could barely consider it a stealth tool. The duration is also quite
scarce, I pointed that out in the original PR too.

Basically, I want to make the item cooler.

## Changelog

🆑
balance: Buffed the duration of the SC/FISHER Saboteur Handgun's
disruption effects. It's also stealthier and it won't conspiciously
alert living mobs hit by it.
add: Added saboteur interactions with radios, pAIs, turrets, secbots and
APCs.
