feat(battle-engine): full-surface god-object stubs (UIManager/GameObjMgr/BattleLog) 7532->5600

Generate the COMPLETE decomp member surface (not frontier-subset, which silently drops
already-provided members) for UIManager(+ViewScene/ChangeViewSceneParam), GameObjMgr,
BattleLogManager/Item, InPlayCardFrameEffectControl. UIManager/Footer base fixes:
UIManager is MonoBehaviour (singleton kept by hand via --exclude); Footer is the copied
Engine type (removed the conflicting global shim). Add HUDMode enum, Wizard manager
return-type stubs, and a closure-stubs file for 7 referenced empties.
