fix: ripple accumulation bug — add eventTarget option for pointer release listeners

Ripples on state-layer wrappers never faded because pointerup/pointerleave
listeners were registered on the tiny inner span, not the interactive parent.

- Added eventTarget option to createRipple() — routes release listeners
  to a separate element (the parent component)
- Updated checkbox/radio/switch to pass eventTarget: this
- Added 3 regression tests verifying listener placement
