feat(necromancer): add Necromancer mana bar (mana + runic power at once)

Mirrors the Druid mana bar for the CoA Necromancer (class token
NECROMANCER): the main power bar shows the active power type while a
second bar shows the other one, so mana and runic power are both
visible at the same time. Adaptive — recolors to whichever resource it
is currently showing, so it works regardless of which power CoA treats
as primary. Off by default; toggle under Player bars (auto-hidden for
non-Necromancers).
