Tim a6be5d4607 Camera upgrades consume power (#94246) 
## About The Pull Request
Installing camera upgrades now consumes more power. Each form of
upgrade, x-ray, EMP resistance, and motion sensors all increase the
power usage as multipliers. (which means the more upgrades, the more
severe the power drain)

| Upgrade | Power Multiplier |
| ------------- | ------------- |
| X-ray | x10 |
| Motion Sensor | x4 |
| EMP Resistance | x1.25 |

The default power consumption of an active camera is 20. So if you stack
all the upgrades it costs 1K, which is the default power cost for most
station machinery. The power costs are not applied for AI malf upgrades,
so it doesn't give away their antag status. Also this fixes disabled
cameras consuming power.

## Why It's Good For The Game
Upgrading cameras should have a drawback where it requires more power.
This gives engineering more reasons to boost power production.

## Changelog
🆑
add: Installing camera upgrades now consumes more power. Installing
several upgrades onto the same camera has a power multiplier effect that
stacks.
fix: Fix disabled cameras consuming power
