feat: add power bar to boss frames for energy/mana tracking

Browse source 
Energy bosses (e.g. Anub'arak, various WotLK encounters) use energy as
their ability cooldown mechanic — tracking it in the boss frame lets
raiders anticipate major ability casts. Mana, rage, focus, and energy
all shown with type-appropriate colors as a slim 6px bar below HP.
