Speak a shell destination's badge in words, and stop a null offset on PHP 8.5

<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.

 - Slots, each rendered once: `brand` (beside the rail's menu button, expanded only), `rail-header` (a FAB), `rail-footer` (pinned to the foot of the rail), `actions` (a row of icon buttons at the very foot, stacked when collapsed), `top` (the app bar, above the page at every width), and the page. `label` names the landmarks ("Main"); `rail-width` is the expanded width (`16rem`).
 - The rail is one element at every width: what is in it is also what a phone sees in the modal rail. Below `sm` nothing opens it but `$store.rail.show()`, so a page whose destinations are not all in the bar needs a menu button in its app bar (hidden from `sm`).
 - Below `sm` the shell sets `--material-bottom-bar` (the bar, the bottom safe area and `--material-bottom-extra`), so the snackbar, a `fab` button and the page's bottom padding clear the bar; pad anything else you pin to the bottom with it. See Safe areas.
