fix(theme-studio): open the picker crosshair on the current color

openPicker positioned the crosshair while the picker was still display:none, so its client dimensions read 0 and the crosshair pinned to the top-left corner instead of the shown color. I moved display:block ahead of paintPicker so the element has layout when its size is read, then added a headless #cursortest that opens the picker on a saturated color and checks the crosshair lands off-corner.
