port(m1): wave 7f — VFX containers / Create factories / dropped event / ctor cascade (112->88)

- VFX: SequentialVfxPlayer.GetAllVfxAsList, ParallelVfxPlayer.GetVfxList,
  VfxMgr.CheckAndAddEffectVfxList; point our own ShowBattleUIImmediatelyVfx stub at
  NullVfx.GetInstance() (it called a non-existent NullVfx.Create).
- Static factories: SkillTargetSelectTouchProcessor.Create (10-arg),
  DialogReportToManagement.Create(long).
- Re-add StartSkillSelectVfx.OnStart event (m1_stub_gen drops `event` decls — the
  recurring session-6 gap; generator event-capture fix still pending).
- Stop the BattleCardView/GameObjMgr ctor cascade: parameterless ctors on the no-op
  BattleCardView and GameObjMgr hand shims so non-chaining subclass/field stubs satisfy
  their implicit base() call.
- Copy Cute/ListExtensions.cs (FisherYatesShuffle extension) verbatim into Engine.
