Let an application replace the safe-area insets and dock on the bottom bar

Components read the device's safe-area insets straight from env(), which a
browser test cannot fake and an application drawing its own status strip
cannot extend. Every inset the package reads, in its CSS and its views, is
now var(--material-safe-top|bottom|left|right, env(safe-area-inset-…)):
unchanged while the variables are unset.

The app shell's --material-bottom-bar also adds
var(--material-bottom-extra, 0px), so an application that docks something on
the phone's navigation bar (an offline banner) sets its height once and the
snackbar, a fab button and the page's bottom padding clear it.

A guard test fails on any env(safe-area-inset-*) outside such a variable, and
AppShellTest's assertion on the bar height's class follows the new value.
