_0Steven 18c346274e Ethereals: Standardize defines, lower hunger rate, refactor charging methods (#88960)
## About The Pull Request

Man.

### Standardizing Ethereal Defines

The _single_ biggest issue with all of the recent Ethereal prs has been
that, well, none of our Ethereal defines meaningfully tie to each other,
and as shown repeatedly it's _incredibly_ easy to the others when
changing one of them.
To resolve this, we introduce a `STANDARD_ETHEREAL_CHARGE` define that
every single other Ethereal define is scaled around, which itself is
tied to `STANDARD_CELL_CHARGE`.
Now these can be changed without immediately blowing up everything else,
and with awareness that they tie back to something.

As a side to this, we redefine all reagent-based charge recovery to be
relative to `ETHEREAL_DISCHARGE_RATE` rather than an arbitrary power
level, so it's easier to compare them to how quickly an ethereal
discharges.

### Adjusting Ethereal Defines

Previously, we defined `ETHEREAL_DISCHARGE_RATE` as `8e-3 *
STANDARD_CELL_CHARGE` per second, while defining `ETHEREAL_CHARGE_FULL`
as `2 * STANDARD_CELL_CHARGE`.
With some math, we get that we'd `2 / 8e-3 = 250 seconds`, 4 whole
minutes, to go from full charge to none at all.
It only takes half as much to get hungry, and about 3 minutes to start
taking toxin damage from roundstart.
So we slash this by eight, to `1e-3 STANDARD_ETHEREAL_CHARGE`, giving us
a nice 16-17~ minutes until we're hungry, and another 16-17~ until we
are 100% out of charge. This is also closer to the pre-power-rework
discharge rate.

What made this _worse_ was that the Ethereal APC charge define
`ETHEREAL_APC_POWER_GAIN` wasn't updated to match the current
charge/discharge levels, still being at `10 * STANDARD_CELL_CHARGE`,
which due to how it was coded led to it being impossible for Ethereals
to recharge from APCs.
We first and foremost change this to `0.1 * STANDARD_ETHEREAL_CHARGE`,
which is roughly equal to what it was before the most recent change, and
actually falls in line with Ethereal charge levels.

### Refactoring Ethereal Charge Methods

APC and Power Store recharging were both performing some awkward checks,
which led to our primary issues above, where they would refuse to even
attempt to charge if the stomach couldn't handle a full load or the cell
didn't have a full load.
So we rewrite their entire method to instead check how much can be
charged by taking the minimum of the cell charge, stomach used charge,
and charge-per-step.
We do this instead of just discharging it and taking the return value,
as the stomach may not have enough space for the cell's power, and
that'd get wasted.

This rewrite also allows us to address a small list of bugs.
We keep the `to_chat` for power store draining, as it better
communicates that this method is imperfect than a balloon alert would.

# Testing:<br>I spent an extended period of time looking at Ethereals
slowly starve in front of me with a stopwatch in hand.

## Why It's Good For The Game

Fixes #88934.
Fixes #88977.
16-17~ minutes is a _lot_ more bearable than 2-3~ minutes, and more in
line with discharge rates before the power rework.
Having Ethereal charging stuff actually work is nice.

## Changelog
🆑
balance: Ethereal hunger rate has been adjusted to be 1/8th of its
previous rate, now taking roughly 16-17~ minutes to go down from full to
normal or normal to none. Ethereal defines have been standardized to
help keep this sane.
refactor: Ethereal APC and power store draining/charging methods have
been refactored. Please report any issues.
fix: Ethereal APC and power store draining/charging no longer
arbitrarily caps out at slightly below or above the max/min.
fix: Ethereal APC draining/charging no longer runtimes when there is no
cell or it gets removed mid-charge.
fix: Ethereals can no longer continue charging their stomach even if it
gets surgically removed from them mid-charge.
fix: Ethereal power store draining actually updated the charge level
overlay.
qol: Ethereal APC and power store draining displays a balloon alert when
it can't continue for whatever reason.
