ui: add battleground score frame for WSG/AB/AV/EotS/SotA

Browse source 
Renders a compact top-centre overlay showing Alliance vs Horde scores
when the player is in a recognised battleground map.  Score values are
read directly from the world state map maintained by SMSG_INIT_WORLD_STATES
and SMSG_UPDATE_WORLD_STATE, so no extra server packets are needed.

Supported maps:
  489 – Warsong Gulch    (flag captures, max 3)
  529 – Arathi Basin     (resources, max 1600)
   30 – Alterac Valley   (reinforcements, max 600)
  566 – Eye of the Storm (resources, max 1600)
  607 – Strand of Ancients
