Fix: refactor mercenary mech parts (#619)

P.s. Юджин сделал костылём, я бы честно говоря не трогал combat chasis
вообще, наследование у премейдов грешно.
Данный ПР даёт меху батарею на 3000, осветительные приборы, а так же
отрывает от combat меха, от греха подальше.
(прописывается отдельный premade)
Вот предложка:
