<x-app-shell> passed no badge label to its rail and bar items, so a badge
like 0/3 reached a screen reader bare; a destination's badgeLabel now does.
The head script indexed the profiles with a null scheme when none are
configured, which PHP 8.5 reports as a deprecated null array offset on every
page with theme.meta on. It reads the default scheme without the lookup.
