Keep a closed standard side sheet out of its row from the first paint

A closed standard sheet is `inline-size: 0` with a negative margin as
wide as its row's gap, but the view writes that gap (`--md-drawer-gap`)
and `data-md-drawer-collapsed` only once Alpine runs. Until then each
closed sheet was a zero-wide flex item that still cost the row one gap,
and a sheet bound to an open Livewire property had no width at all, so
the content beside them changed width when the script started - two
closed sheets beside a column made it 48px narrower, then it jumped.
Until the view has settled, drawer.css now takes a standard sheet that
is not `data-md-open` out of the layout, and the view renders
`data-md-open` on a standard sheet whose `wire:model` property is open
(truthy as Alpine reads it), so it stands at its width from the first
paint. Transitions still wait for `data-md-drawer-settled`. A browser
test measures a column beside two closed sheets (one bound to Livewire,
one to Alpine) and an open one before Alpine starts and once settled;
it fails without the change.
