Draw the snackbar host without Tailwind

Browse Source 
Plan step 36 (actions). <x-toast> renders data-md-toast with
data-md-position, its snackbar data-md-toast-snackbar with a bound
data-md-two-line, data-md-toast-content with a bound
data-md-toast-wrap, and data-md-toast-action/-dismiss; no class list.
toast.css draws SnackbarTokens' inverse surface, 48/68px container,
the two 40px controls reaching 48px targets with their own state
layer and touch target (ACT-18), the enter transition and the
position-start margin that grows from medium.

data-toast becomes data-md-toast-snackbar and data-toast-action
becomes data-md-toast-action (snackbar.js, navigation.js's
hide-on-scroll guard, NavigationBarTest, CommunicationTest); a new
data-md-toast-dismiss hook names the close button. ToastTest is
rewritten on the hooks and ComponentStylesheet. CommunicationTest
gains the owed tests: an actioned snackbar past the default timeout,
Escape on a focused one, the live region before any message, and the
two-line height with Alt+G reaching the action from elsewhere on the
page.

The live region is the host itself, not the snackbar: a region must be in the page before its
contents change for a screen reader to announce them reliably, and the snackbar comes and
goes. It is `aria-live="polite" aria-atomic="true"`, as M3 asks for a snackbar (never
assertive); a `type` picks the region's role — `alert` for an error or a warning, `status`
otherwise — and the explicit `aria-live` keeps even those polite.

Hooks for tests and styling: `data-toast` on the snackbar on screen, `data-toast-action` on its
action button.

`@persist` keeps the host across wire:navigate, so a toast dispatched with `redirectTo` is
still on screen when the next page arrives.
There is no state icon: M3 says to avoid one in a snackbar ("use a dialog instead if an icon
feels necessary"), and both lines of the message are plain inverse-on-surface — M3 gives the
supporting text no fourth colour and tells the two lines apart by position. The 40px action
and close buttons carry `touch-target`, which reaches M3's 48px without growing the container.
