feat(battle-engine): CRI/Unity overload + generated base-ctor fixes (1586->1556)

CRI: CriAtomExPlayer.AttachFader, CriAtomCueSheet.acb, CriAtomExCategory static.
Unity overload gaps (CS7036): Transform.Translate/Rotate(float,float), Vector4(3/2-arg)
ctors, Vector3 instance Scale. Parameterless ctors for generated Vfx bases (ForecastIcon
VfxBase/ShowChantCountVfx/EvolveVfx) whose derived stubs' implicit base() failed.
