Rename the paintjob recipe defs to the new `FCP_Paint_*` scheme, update the power armor station to reference them directly, and add restore-original recipes for painted T-51 and T-60 armor and helmets. This also removes the conditional recipe-user patch wrapper and tweaks power armor, helmet, and frame draw sizes for larger in-game visuals.
Introduces new XML recipe definitions for T-51 and T-60 power armor and helmet paintjobs, and adds a new ApparelUpgradeableBase parent for upgradeable armor. Updates power armor and helmet ThingDefs to use the new parent, removes embedded recipeMaker/costList from paintjob variants, and adds repairable-at-station comps to all relevant armor and helmet definitions.
