NTNet airlocks (#35947)

* Standardizes access checks

* Makes SS Networks init before SS Atoms to prevent NTNet interfaces from initializing before them

* Adds passkey support to NTNet packets

* Adds NTNet support to airlocks, makes door remote use NTNet

* Access levels given by jobs are now shuffled

* Access code improvements

* Adds IC card readers

* Fixes a delay issue with opening/closing airlocks with NTNet or signalers

* code review memes

* Renames plaintext_passkey to encrypted_passkey

* death by thousand nitpicks
