Bugfix Rebalance: Chem storage charges faster and gets a roundstart boost

[antlersss]

About the pull request

Attempts to somewhat counteract the nerf to roundstart energy generation caused by the #12270 bugfix by both halving the length of chem storage's recharge cooldown (also doubling its energy consumption), as well as adding a boost to reagent generation during roundstart (<00:20 round time) that quadruples reagents generated.

Also cleans up some defines that were not used outside of their files.

Explain why it's good for the game

The bugfix that removed the chem storage completely refilling itself upon a new medic latejoining disproportionately nerfed the capacity of chemline doctors to properly handle the influx of requests during roundstart. Previously, they had access to the trickle of latejoining corpsmen during roundstart that refilled the storage and slowly tapered off as the round went on. Now, the regeneration of chemicals is nearly completely linear, without regard to the high demand and traffic that still exists roundstart.

This PR seeks to allow doctors to handle that surge of corpsman with the efficiency that they previously were able to do, as well as generally buffing reagent generation through reducing its recharge cooldown.

balance: Chem storage's recharge cooldown has been halved, overall doubling reagent production (and power usage)
balance: The medical chem storage machine receives a boost to production during roundstart, tripling its output until 00:20 roundtime

the limit is by design and the other PR soft removing it was the unintended part. It will probably take some time for mmedic players to re-adjust to not being able to have unlimited line chems available and during that time it may be more frustrating to have less or longer lines as people still order as though its the bugged capacity.
