feat(battle-engine): app-type wave (RoomBase/Avatar/BossRush/tasks) 4850->4572

Full-surface stubs for RoomBase, Avatar/BossRush/MyRotation battle-log items (MonoBehaviour),
GetDeckDataFromCode, MailTopTask, AccountTransferHelper, CanNotTouchCardVfx. EXCLUDE
inherited overrides (CanNotTouchCardVfx.IsEnd, MailTopTask.Parse). ClosureStubs for the
RoomMatch subsystem bleed (~11 Room* types) + AppleLogin(+Error). Reward/Event deferred
(ambiguous common names resolve to wrong SDK files).
