/**
 * `password.confirm`, answered in place for the app's own screens.
 *
 * The framework's version redirects to the confirm-password screen and
 * relies on the "intended" URL to come back. For a GET that works. For
 * the writes this guards it cannot: Redirector::guest() only remembers
 * the exact URL of a GET, so a POST comes back to the page it was sent
 * from, freshly rendered, and whatever was typed into the form -- a
 * token's name and scopes, a release reason -- is gone, along with the
 * action itself.
 *
 * So an Inertia request gets a 423 instead, which the browser turns into
 * a password dialog over the page it is on (password-confirmation-dialog.tsx).
 * Nothing navigates, the form keeps its state, and once the password is
 * proved the same request is sent again. The check itself is the
 * framework's, unchanged: this only decides what the refusal looks like.
 * Anything else -- a plain form post, a JSON client -- is answered
 * exactly as before.
