Adds charge checking interactions to ethereals (#96904)

## About The Pull Request
This PR adjusts the ethereal stomach equivalent (biological batteries)
such that they provide their charge whenever either they or their mob
owner get hit by a multitool. This is formatted in the exact same way as
seen when multitooling a cable. A tip of the round indicates that this
is possible.

Additionally, health analyzers will show stomach charge as well. While
coding this I made a couple of slight adjustments to the nearby blood
level formatting for spelling and a (sometimes) stray comma. In effect
this makes it go from displaying "Blood level: 100%, 560 cl, <ins>type:
O+</ins>" to "Blood level: 100%, 560 cl <ins>O+</ins>" (with the
underlining being a tooltip).
## Why It's Good For The Game
To my knowledge, there is currently no way to get the exact and
quantified charge of an ethereal. This makes it difficult for anyone
healing an ethereal to definitively tell whether toxins damage is from a
lack/excess of charge or some other source.

Aside from that, it's also just mildly comedic to be able to check the
charge of a living entity in the exact same way as a piece of insulated
copper.
## Changelog
🆑
add: Health analyzers now display ethereal charge.
add: It is also possible to check the charge of an ethereal (or their
stomach equivalent) with a multitool.
