Hardsuit interface overhaul (#22403)

**Summary**
Converts hardsuit NanoUI to TGUI and overhauls much of the associated UI
and module code.

The conversion alone is what necessitated quite a bit of cleanup of our
11-year-old hardsuit code, for which I leaned heavily upon tg's
implementation of MODsuits. Therefore, this is a PARTIAL (???) port of
both https://github.com/tgstation/tgstation/pull/59109 and
https://github.com/tgstation/tgstation/pull/77022. While a lot of
wonderful code and UI design was ported 1:1 (for which I am grateful!),
our hardsuits are still NOT MODsuits. Most of our back-end remains the
same.

Fixes https://github.com/Aurorastation/Aurora.3/issues/22071

changes:
  - refactor: "Migrates Hardsuit NanoUI to TGUI."
- refactor: "Updates Hardsuit module type definitions, configuration
data, many misc other functions for the purpose of the UI refactor
(general utility and readability improvements)."
- balance: "Hardsuits now passively consume a small amount of energy
while online, even when retracted."
- balance: "Hardsuit boots can no longer be retracted without also
retracting the chest piece first."
- balance: "Mounted hardsuit storage module max space increased from 9
to 14."
- balance: "Plasma cutter (standalone and mounted) damage increased and
range decreased by 50% each."
- soundadd: "Adds several new sounds for hardsuit use (attribution
located w/ files)."
- code_imp: "Makes power_wattage_readable() a global proc and adds
power_joules_readable()."
  - code_imp: "Lots of misc DMdoc updates."
- bugfix: "Synthetic Charging Stations now charge hardsuit power cells
as intended."
