Rewrite minimap to use pre-baked BLP tile textures from MPQ archives

Browse source 
Replace the 3D top-down rendered minimap with WoW's native pre-rendered
BLP tile textures loaded via md5translate.trs. Tiles are composited into
a 3x3 grid FBO with proper axis transposition matching the ADT terrain
convention. The screen shader provides camera-rotation, circular mask,
directional player arrow, and 20% transparency. Minimap is now on by
default with the N toggle key removed.
