Rewrite the error pages without Tailwind

Browse Source 
Plan step 36 (containment group, error pages): errors::minimal's class
lists move into resources/css/components/error-page.css, keyed on
data-md-error-page/-art/-shape/-code/-headline/-message/-actions;
body carries no hook of its own and is styled by a bare `body`
selector, matching how ErrorPage::fallbackStyles() already styles it
(no other rewritten view is a full HTML document). The section
contract (title, code, headline, message, shape, actions) and the
framework's 401/402 compatibility are untouched, since neither depends
on a class or a hook. The shape's <x-shape> (a component outside this
batch, and one with no "fill the parent" prop) is coloured and sized
to its container by a plain `svg` descendant selector rather than a
class or a new prop. The page's font stays a literal system stack, not
var(--md-ref-typeface-brand): Tailwind's own `font-sans` utility this
replaces was never the brand font either
(resources/css/tokens/theme.css's --font-sans is the only utility
that is), and an error page must read before any webfont has loaded.

ErrorPage::fallbackStyles() draws onto the same hooks, renamed the
same way (data-error-* -> data-md-error-*, data-error-fallback ->
data-md-error-fallback) so the no-build path keeps working; how it is
built (a hand-written heredoc, not Stylesheets::bundle()) is
unchanged, per step 40. Updated in the same commit:
tests/Feature/ErrorPagesTest.php and tests/Browser/ErrorPagesTest.php.

The error pages' views live outside resources/views/components/, so
they are not in ContainmentStylesheetsTest's dataset (its "imports
what its view renders" check reads a fixed
resources/views/components/<name>.blade.php path); adapted
tests/Feature/ErrorPagesTest.php instead, with the same stylesheet-
shape, import, ViewClasses, token/px-breakpoint and containment-block
checks the dataset gives every other component.

Imported from the Containment block of components.css.

/*
* `errors::minimal`: the layout the package's 403/404/419/429/500/503 pages and the framework's
* own 401/402 (which extend this layout, `src/Support/ErrorPage.php`'s docblock) render through.
* A page's own `@section`s fill `title`, `code`, `headline`, `message`, `shape` and `actions`
* (`resources/views/error-pages/errors/minimal.blade.php`'s header) — none of that is this file's
* concern, only the geometry and colour of the parts that show them:
*
* body
* [data-md-error-page]
* [data-md-error-art]
* [data-md-error-shape] an <x-shape>, turning once a minute unless reduced motion asks
* otherwise (its `svg` fills the art box and is coloured here,
* since <x-shape size> only takes a fixed px, not "fill parent")
* [data-md-error-code] the status, in display type over the shape
* [data-md-error-headline] what happened
* [data-md-error-message] one sentence on what to do, only when `headline` is its own
* section (otherwise `message` doubles as the headline)
* [data-md-error-actions]
*
* `body` carries no hook of its own — `src/Support/ErrorPage.php`'s `fallbackStyles()`, the
* stylesheet an application without a Vite build gets instead, styles the bare element the same
* way, so this file matches it rather than inventing a hook the fallback has no equivalent of.
* That fallback still needs updating by hand when this file changes, until step 40 replaces how
* it is built.
*
* The page's own font is a literal system stack, not `var(--md-ref-typeface-brand)`: an error
* page must read correctly before any webfont has had a chance to load (`@font-face` is what the
* fallback path has none of, and this file matches it even on the path that does), and Tailwind's
* `font-sans` this replaces never carried the brand font either
* (`resources/css/tokens/theme.css`'s `--font-sans` is the only utility that does).
*
* Colours from the roles (`docs/reference/m3/styles.md` § Typography, "Accessibility
* requirements": surface/on-surface); the display code over its primary-container shape is the
* pairing `docs/audits/m3-alignment/containment.md`'s "Aligned" section confirms; 24px page
* gutters and the 600px growth of the art and headline are the same numbers the audit found
* clean. `--md-sys-typescale-emphasized-display-lg` is the code's weight and roundedness; the
* shape's 60s linear turn has no motion token (`--md-sys-motion-*` pairs a duration with a spring
* for a state change, not an ambient loop) and stays a literal, gated the way the audit's
* "Aligned" section already found it: behind `prefers-reduced-motion: no-preference`.
