Bug 36454: (follow-up) Tweak CSS and add restricted status output

This patch makes some tweaks to the style of the new information: We can
use the Bootstrap 5 "badge" class and "warning" style to get the
appearance we want.

This patch also adds output of the patron's restricted status if
present.

To test, apply the patch and rebuild the staff interface CSS. Perform a
patron search (from the checkout header search form for instance) and
confirm that a "restricted" badge appears alongside the branch and
expired badge.
