Rewrite the drawer (side sheet) without Tailwind, remove pane

Plan step 36 (containment group): <x-drawer>'s class lists move into
resources/css/components/drawer.css, keyed on data-md-drawer (with
data-md-open, data-md-standard) and data-md-drawer-scrim/-sheet
(data-md-side)/-head/-head-row/-heading/-title/-subtitle/-close/-body/
-actions. The modal sheet slides in on the emphasized-decelerate
easing and out on emphasized-accelerate (an asymmetric CSS transition
expressed by giving the open-state selector its own
transition-duration/-timing-function, which the "after-change style"
rule picks up); the sheet stays x-show-driven, with @starting-style +
transition-behavior: allow-discrete taking the place of x-transition's
enter/leave classes, matching resources/css/components/search.css's
already-rewritten scrim/view. A standard sheet drops the scrim and
trap from 840px and only fades in place (an in-flow box does not
travel); data-md-drawer-collapsed (from the view's `wide` Alpine
state) takes it out of the layout while closed there.

<x-drawer pane> is removed: step 35's <x-list-detail> is M3's form of
that job (the plan's decision, docs/plans/material-3-alignment.md
"Decisions"). Removed the prop, its CSS classes and its tests
(OverlayTest's two pane-only tests deleted, the others' pane cases
dropped); pointed each mention at <x-list-detail> in the material-3
guideline, the material-3-design and livewire-material-development
skills, and added a line to UPGRADE.md's 2.0.0 notes. No other living
file named `<x-drawer pane>` (grepped views, tests, README, boost,
workbench excluding build output); docs/plans and docs/audits keep
their history unchanged.

Imported from the Containment block of components.css, importing
button.css and divider.css for what the view renders.

 ### Layout and breakpoints
 - Widths are M3's window size classes, the only variants that compile: compact below 600px (the default), `medium:` 600, `expanded:` 840, `large:` 1200, `extra-large:` 1600, and `max-medium:` … for "below". In scripts, `from()` and `upTo()` from `resources/js/breakpoints.js`.
-- What changes per class: compact — navigation bar, one pane, full-screen dialogs, a bottom sheet for choices; medium — collapsed rail, one pane; expanded — rail (collapsible), two panes, menus and basic dialogs; large and extra-large — the rail expanded, two panes, a third only at extra-large as a side sheet. `<x-scaffold>` does this; content lives in panes (`<x-drawer pane>`), never beside the rail by hand.

 - Margins are 16px below `medium` and 24px from it; spacing sits on the 4px grid, as padding and gaps on the parent, with margins only between layout regions. A fixed pane is 360px (expanded) or 412px (large); a side sheet at most 400px.
 - Write logical properties (`ps-*`, `me-*`, `start-*`, `text-start`); directional icons mirror in RTL; charts and media controls stay LTR. Keep controls inside the safe area (`--material-safe-*`).
