## About The Pull Request

Made a new UI and refactored some mech code in the process.

Fixes #66048
Fixes #77051
Fixes #65958 ??? if it was broken
Fixes #73051 - see details below
Fixes other undocumented things, see changelog.

## Why It's Good For The Game

The UI was too bulky and Mechs were too complex for no reason. 
Now they follow some general rules shared between other SS13 machinery,
and there is less magic happening under the hood.

## Detailed Changes

### New Mech UI, Air Tank and Radio as separate modules

Previous UI for comparison:

Previously mechs came with radio pre-installed and air canisters
magically pre-filled with air even when you build one in fab.
Radio and Air Tanks are now both utility modules that are optional to
install. Gas RCS thrusters still require Air Tank module to operate.

This made the Mechs more barebones when built, giving you only the basic
functionality.

To compensate this change, all mechs got two extra utility module slots.

All other modules got new UI. And ore box now shows the list of ores
inside.

### Mounted Radio

Works as a normal radio, but with subspace transmission. Available from
the basic mech research node and can be printed in fab.

### Cabin Sealing

To compensate for the lack of air tank by default, mechs with enclosed
cabin (e.g. all except Ripley) got an ability to toggle cabin exposure
to the outside air. Exiting the mech makes cabin air automatically
exposed.

When you seal the cabin, it traps some of the outside air inside the
cabin and you can breathe with this air to perform a short space trips.
But the oxygen will run out quickly and CO2 will build up.

Sealing the cabin in space will make the cabin filled with vacuum, and
it will stay there until you return to air environment and unseal the
cabin, letting the breathable air to enter. There are temperature and
pressure sensors that turn yellow/red when the corresponding warning
thresholds are reached.

You could also use personal internals in combination with cabin sealing
for long space travels, so Air Tank is completely optional now and
mostly needed when you need RCS thruster.

### RCS thrusters

They are now available earlier in tech tree and consume reasonable
amount of air (5 times more than human jetpacks), and they don't work
without Mounted Air Tank, unless it's an Ion thruster variant.

### Mounted Air Tank

Available from the basic mech research node and can be printed in fab.
Built model comes empty, and syndicate mechs come with one full of
oxygen.

<img alt="GrFDrH5Hwe"

Can be switched to pressurize or not pressurize the cabin. Releases gas
only when the cabin is sealed shut. Starts releasing automatically, but
can be toggled to not release if you want to use it just as a portable
canister.

Cabin pressure can now be configured in the module UI instead of
Maintenance UI.

Can be attached to a pipe network when the mech is parked above a
connection port.

Comes with a pump that works similarly to the portable pump. It lets you
vent the air tank contents outside, or suck air from the room to fill
the air tank. Intended to provide an ability to fill the air tank
without the need to bother with pipes.

Also has gas sensors that display gas mix data of the tank and the cabin
(when sealed).

### Stock part changes

All mechs now require a servo motor and they reduce mech movement power
consumption instead of scanning module.

Scanning modules are optional for mech operation (still required to
build) and the lack of one disables the following UI elements:

- Display of mech integrity (you can still see the alerts or examine the
mech to get rough idea)
- Display of mech status on internal damage (and you can't repair what
you can't diagnose)

The rating of scanning module doesn't have any effect as of now.

Cargo mech comes without it roundstart.

src="https://github.com/tgstation/tgstation/assets/3625094/147144ca-824e-4501-acf5-6ee104f309e7">

Capacitors now also reduce light power usage and raise the overclocking
temperature thresholds (see below).

### Maintenance

Maintenance UI removed, and its logic migrated to other places.

Access modification now managed inside the mech, and anyone who can
control the mech, can adjust the access in the same way as they can set
DNA key.

To open the maintenance panel you just need a screwdriver. It is instant
when the mech is empty and it has a 5 second delay when there is an
occupant to avoid in-combat hacking and part removal. It will alert the
occupant that someone is trying to tinker with their mech.

Once the panel is open, you can see the part ratings:


![image](https://github.com/tgstation/tgstation/assets/3625094/404f95bb-9f74-4e5b-a975-5ab6f74bdfa9)

With open panel you can hack the mech wires (roboticists can now see
them):

<img alt="mj205G2qDa"
src="https://github.com/tgstation/tgstation/assets/3625094/44cea0d1-44b4-4b50-b1d3-a97c0056bab3">

There are wires for:
- Enabling/Disabling ID and DNA locks
- Toggling mech lights
- Toggling mech circuits malfunction (battery drain, sparks) 
- Toggling mech equipment malfunction (to repair after EMP or cause
EMP-like effect, disarming mech)
- 3 dud wires that do nothing

The hacker may be shocked if the mech power cell allows.

When the panel is open and the user has access to the mech, they can
remove parts with a crowbar:

<img alt="jR40gyTWtJ"
src="https://github.com/tgstation/tgstation/assets/3625094/b573f5b9-b8ea-412e-b3e0-c872e01e0c23">

Hitting the mech with an ID from outside now toggles the ID Lock on/off
if the ID has sufficient access.

### Power consumption and overclocking

Rebalanced mech power consumption. T4 parts were not working in
Syndicate Mechs, as their effect was not calculated until you manipulate
parts manually. Constructed mechs with t1 parts even had their energy
drain reduced with upgrade to t1.

Now all mechs apply their base step power usage correctly don't ignore
the stock parts.

Servo tier now reduces base power consumption by 0% at t1, 50% at t2,
33% at t3 and 25% at t4
Capacitor tier now reduces base power consumption of mele attacks,
phasing and light by the same amounts.

Gygax leg actuators overload replaced with mech overclocking. Any mech
can be overclocked by hacking wires, but only Gygax has a button for
toggling it from the Cabin.

Now there is an overclock coefficient. 1.5 for Gygax and other mechs, 2
for Dark Gygax.

When overclocked, mechs moves N times faster, but consumes N times more
power.


![image](https://github.com/tgstation/tgstation/assets/3625094/01e285fd-6fd6-4558-8277-2ed3abf474d8)

While overclocked, mech heats up every second, regardless of movement,
and starts receiving internal and integrity damage after a certain
temperature threshold. The chance is 0% at the threshold, and 100% at
thresholds * 2. The roll happens every tick. Capacitor upgrades this
threshold, letting you overclock safely for longer periods.


![image](https://github.com/tgstation/tgstation/assets/3625094/80d90cea-0d20-4054-9369-a47deb6f52f2)

When you stop overclock, the temperature goes back down.

### Other changes and fixes

Concealed weapon bay now doesn't show up when you examine the mech, so
it's actually concealed now.

New radio module can properly change its frequency, as it didn't work
for previous radio.

Launcher type weapons were ignoring cooldowns and power usage, so you
could spam explosive banana peals, while they should have a 2 second
cooldown:
<img alt="q5GjUsHwGr"
src="https://github.com/tgstation/tgstation/assets/3625094/d102725d-e9e1-4588-9d6c-b9e38b7a6535">

Now this is fixed and all launcher type weapons properly use power and
have their cooldowns working.
And now they have the kickback effect working (when it pushes you in the
opposite direction in zero gravity on throw).

Thermoregulator now heats/cools considering heat capacity instead of
adding/reducing flat 10 degrees. So you can heat up cabin air quicker if
the pressure is low.

There were some other sloppy mistakes in mech code, like some functions
returning too early, blocking other functionality unintentionally. Fixed
these and made some other minor changes and improvements.
