Draw the app bar without Tailwind

Browse Source 
Plan step 36 (navigation group, first stream): <x-app-bar>'s class
lists move into resources/css/components/app-bar.css, keyed on
data-md-app-bar (with data-md-variant/-sticky/-subtitled/-scrolled/
-collapsed) and its parts data-md-app-bar-row/-leading/-headline/
-title/-subtitle/-search/-trailing/-action/-overflow/-expanded. The
overflow menu (two icon buttons below 600px, four from it, N-09's
312px search cap and N-11's three-column centred row) already matched
the audit; only its hooks, units and layer needed to change. Every
length is px, spacing through the measurement tokens where one
matches (M3's own "4dp leading/trailing space" and "16dp" headline
inset had no exact token, so those stay literal). Imports button.css,
menu.css and menu-item.css for the overflow menu the view renders.

Hooks renamed: every unprefixed data-app-bar-* attribute and
data-scrolled/data-collapsed to data-md-*, updated in
tests/Feature/Components/{AppBarTest,PaneTest}.php and
tests/Browser/{BarsTest,NavigationTest}.php. app-bar.js needed no
change: it reads the bar through $root, not by hook name.

tests/Feature/Components/NavigationStylesheetsTest.php is the
navigation twin of ContainmentStylesheetsTest.php, on the same
tests/Support/ViewClasses.php rule; its dataset starts at 'app-bar'
and a 'tabs' entry (once that commit lands) will read both
tabs.blade.php and tab.blade.php, since they share one stylesheet.

Added the owed browser tests (docs/plans/material-3-browser-tests.md):
the overflow at 599/600px, keyboard in its menu, a menu closing once
its width no longer shows it, and a wire:click action from both the
icon button and the menu item form.
