[MIRROR] Named barrels [MDB IGNORE] (#21850)

* Named barrels (#75976)

![dreamseeker_qLlw7wAl94](https://github.com/tgstation/tgstation/assets/3625094/747f61a0-533f-4cc2-ac61-2901d2d3afb4)

## About The Pull Request

Barrels are nice stationary reagent containers, but it's hard to use
many of them because they're non-transparent and to see the reagents
with science glasses, you need to open the lid.

Now you can name barrels to not mistake them.

## Why It's Good For The Game

You don't need to open the barrel to figure out what you're going to get
from the tap.

## Changelog

🆑
qol: You can name barrels with a pen now, changing its icon
