Fix ported-component styling regressions

Two visual regressions from the custom-element port:

1. The played-row nested its dropdown menu (which contains <button> options)
   inside the toggle <button>. A <button> may not contain another <button>;
   the HTML parser force-closes the toggle on the nested button, and the
   source's explicit </div> tags then close ancestors early — ejecting the
   Purchases/Sessions/etc. sections out of the centered max-w container
   (they rendered full-width). Make the menu a sibling of the toggle, wrapped
   in a relative div so it still anchors under the toggle.

2. Both selector toggles dropped the original
   `flex flex-row gap-4 justify-between items-center` wrapper around their
   content, so the chevron stacked under the label (the GameStatus label is a
   display:flex block). Restore the wrapper — chevron sits on the right with
   proper spacing again.

Verified by screenshot: sections back inside the centered container; both
dropdowns render correctly.
