Fix dropdown item spacing + played-row button alignment

- Selector menu options were bare <button>s with no padding, so the open
  dropdown items were cramped. Add a shared option class (block w-full
  text-left px-4 py-2 + hover), matching the original <a> list items.
- The played-row's relative menu wrapper was a block div, so in the inline-flex
  button group the chevron toggle sat lower than the count button. Make the
  wrapper inline-flex and the group items-stretch so the two buttons align into
  one rounded group again.
- Rebuild base.css for the newly-used utilities.
