fix(switch): restore pad cursor in Touch Controls and launcher overlays

Opening Touch Controls dropped the launcher virtual cursor and swallowed
gamepad input while touch still worked. Share PadCursor with the save
editor, forward pad events, and centralize overlay handoff/resume so both
hosts park and re-arm the pointer cleanly.
