feat(battle-engine): VfxWith ctor arg order + Unity conversions + ITouchProcessor reattach (1102->958)

- VfxWith<T> ctor params were swapped ((T,VfxBase) vs decomp (VfxBase,T)) -> ~38
  CS1503 across SkillCollectionBase/BattleCardBase skill-processing (ProcessInfo
  <-> VfxBase). These are on the resolution path. Fixed to match decomp.
- UnityEngine primitives: implicit Vector3/Vector2<->Vector4 + Color->Color32
  conversions; Transform.Translate/Rotate(Vector3,Space) overloads (iTween).
- ITouchProcessor was dropped from touch-processor stubs by base-clause recovery;
  re-attach via Shim/View/TouchProcessorIfaces.cs (interface-only for generated
  full-surface stubs, interface+no-op members for the empty hand stubs).
