Rewrite the card without Tailwind

Plan step 36 (containment group): <x-card>'s class lists move into
resources/css/components/card.css, keyed on data-md-card (per variant),
data-md-card-figure/-body/-header/-heading/-title/-subtitle/-menu/
-content/-actions. A row (data-md-list-row) renders the shared
md-state-layer and md-focus-ring classes for its tint and ring
(foundation/interaction.css) instead of copying their rules; card.css
adds only the per-state elevation the shared class has no opinion on
(ElevatedCardTokens.kt/FilledCardTokens.kt/OutlinedCardTokens.kt), the
press/hover exclusion for a card's own nested buttons, and the ring for
a non-actionable row whose focus lands on its opener rather than the
card. data-md-dragged is read automatically by the shared class's own
16% tint; card.css only adds its elevation levels 3/4.

Hooks renamed data-list-row -> data-md-list-row, data-list-open ->
data-md-list-open, data-list-actionable -> data-md-list-actionable,
data-dragged -> data-md-dragged, updated in the same commit:
resources/js/search.js and list-rows.js's consumers, table.css's
comment, the showcase (index, data and containment sections),
tests/Browser/ContainmentTest.php, and the development skill's card
and table examples.

Imported from the Containment block of components.css.

/*
* <x-card>: M3's three card variants (ElevatedCardTokens.kt, FilledCardTokens.kt,
* OutlinedCardTokens.kt, androidx Compose Material 3, Apache-2.0; docs/reference/m3
* § Cards → Specs) — filled (surface-container-highest), elevated (surface-container-low at
* elevation 1) and outlined (surface, an outline-variant edge); one 12dp corner for all three,
* which never morphs (M3 specifies shape morph for buttons, FABs and list items, never cards —
* docs/audits/m3-alignment/containment.md, C-23).
*
* A row (`data-md-list-row`, `resources/js/list-rows.js`) renders the shared `md-state-layer` and
* `md-focus-ring` classes (foundation/interaction.css) for its tint and its ring; this file adds
* only what a card needs beyond them:
*
* - per-state *elevation*, which the shared class has no opinion on: elevated 1dp rest → 2dp
* hover → 1dp focus/pressed; filled and outlined 0dp rest → 1dp hover → 0dp focus/pressed
* (the cross-check table's Hover/Focus/Pressed rows). Pressed and focus fall back to the rest
* level, so the `:active` rule (declared after `:hover`, same specificity) resets it even
* while still hovering;
* - the *press/hover exclusion*: a card's own nested button (the "Copy link" in a card that is
* also a row) should light only itself, never the row's tint or elevation. `material.components`
* out-layers `material.base`, so these two rules win over the shared class's plain `:hover`/
* `:active` without needing extra specificity;
* - the *opener-focused ring*: a non-actionable row's focus never lands on the card itself (its
* opener carries the tab stop), so `md-focus-ring`'s own `:focus-visible` never fires for it;
* `:has([data-md-list-open]:focus-visible)` draws the same ring from here instead. An
* actionable card (`tabindex="0"`) is focused directly, which `md-focus-ring` already covers.
*
* `data-md-dragged` (an application sets it while its drag is in progress) is the top of the
* elevation scale — Level4 (8dp) elevated, Level3 (6dp) filled and outlined — under the shared
* class's own 16% dragged tint, which already reads `data-md-dragged` without any help from here.
