[BOUNTY] Re-adds Contractors (#79737)

## About The Pull Request

Adds Contractors back to the game as a kit that Infiltrators (Only
midround/latejoin Traitors, not roundstart) can buy. Buying this will
give you access to the new Contractor items in the uplink (which
replaces the Contractor shop).
I've also refactored things about contractor and how it's handled, such
as removed its sleep calls, swapping its UI to tsx, making it actually
functional within more modern TG code and the reworked Traitors as a
whole, among other things.

I also fixed the contractor guide paper (the text was broken) and made
contractor kit boxes no longer empty.

Contractor items only appear once the contractor kit is purchased, but
they can't be bought until you make an account.

Regular Traitors can't access it

The Contractor UI (Modified to not have a shop anymore) - Ignore the
Invalid Targets, those appear when there's no possible targets

## Why It's Good For The Game

Contractor was a fun way of playing Traitor that isn't relying on RNG
objectives to pop up, this is instead constant stream of content for the
contractor that encourages non-lethal play, and is now a viable
alternative now that Infiltrators don't have Reputation anymore.

## Changelog

🆑
add: Infiltrators (Latejoin/Midround traitors) can now buy and use
Contract kits again.
del: Contractor baton can now only be purchased once.
