Replace the single shared array of 9 effect units with a 2D array of kNumFxSlots × kNumEffectTypes, so each slot owns its own DSP state. This prevents state bleed when the same effect type appears in multiple slots and allows reordering without carrying over internal history. Track activeTypes to skip unchanged slots. Remove the dry buffer since it was unused.
