Sea Select options: disabled-btn contrast + AUTO DRAW scrolls back to the cross

- A disabled OK/DEL × inside a --priUser option chunk blended into it (the global
  `.btn-disabled` bg is also --priUser → no visible circle). Drop the disabled
  btns in `.sea-options-col` to the felt --duoUser so they read as a distinct
  disabled circle, like the deck-stack FLIP ×.
- AUTO DRAW now eases the felt back UP to the cross even when the user already
  OK'd the spread + scrolled DOWN to the options page — so he watches the cards
  land one-by-one. `_chooseSpread(slideIn)`: the OK reveal pins to the options
  (slide-in from above); AUTO DRAW (already chosen) skips the pin + just eases up
  to the cross. `_scrollToCross` now eases from the current scroll position.
- 12 PickSeaUnifiedFeltTest render ITs green.
