Interception&? 1cde8ab0f8 Add smooth transition between hidden and visible pipes (#81800) ...

## About The Pull Request

- Adds smooth transition between hidden and visible pipes, AKA “caps”
and updates automated pipe icon generator to account mentioned changes.
- Adds centering to missed atmos machinery, for example, unary vent is
almost identical to passive, but the second one wasn't centered while
hidden.
- Fixes visual bug with extra and unremovable by normal means pixel
offset on pipes constructed from `/obj/item/pipe`.
- Fixes visual bug with visible cap on a hidden connector. 

I'm really sorry for this mess, but one-line fixes are okay, or are
they?

## Why It's Good For The Game

We're playing atmospherics simulator and pipes play an essential role in
our rounds, people see them all the time and that's why pipes deserve to
look a bit better. This project aims to resolve said issue by adding
transition states, in current implementation they're just cut off when
connected to a hidden segment.
