This PR migrates all tailwind configs in the apps to be CSS configs.
They import a shared CSS Tailwind config from the `config` package
(which in turns imports the old JS config).
The shared JS config will be migrated to CSS in a followup PR.

## Summary by CodeRabbit
* **Chores**
* Centralized Tailwind into a config-driven entrypoint and updated the
app build flow to use the new build step; many apps now import unified
global styles.
* **Style**
* Migrated global styles to a Tailwind v4-style setup, added
project-wide content scanning, consolidated theme imports, standardized
theme tokens (including new --container-site max-width), and added a
small prose utility to remove paragraph margins.

## What kind of change does this PR introduce?
Feature and design-system cleanup. Resolves DEPR-551.
## What is the current behavior?
Admonition supports several overlapping content shapes, but it
previously did not support a first-class success state or
description-only usage cleanly. Title-only usage was also possible,
which made some callouts read like floating headings without body copy.
Docs MDX Admonitions could also pick up prose spacing around rich
children, while the design-system Tailwind config emitted an
ESM/CommonJS warning in the design-system app.
## What is the new behavior?
Adds a `success` Admonition type, description-only support, and a
stricter content contract: `title` or legacy `label` now requires either
`description` or `children`. Existing title-only Studio callsites have
been converted to description-only callouts.
The design-system docs now include examples for description-only and
success Admonitions, plus guidance for `title`, `description`,
`children`, and legacy `label` usage.
This also tightens Admonition body spacing so rich MDX children keep
docs link/code styling without inheriting excessive prose margins, and
renames the design-system Tailwind config to `tailwind.config.cjs` so it
matches its CommonJS syntax.
Warning and destructive alerts now explicitly set `text-foreground`,
preventing nested Admonition titles from inheriting muted
form-description colour after the Tailwind v4 cascade changes.

This PR migrates the whole monorepo to use Tailwind v4:
- Removed `@tailwindcss/container-queries` plugin since it's included by
default in v4,
- Bump all instances of Tailwind to v4. Made minimal changes to the
shared config to remove non-supported features (`alpha` mentions),
- Migrate all apps to be compatible with v4 configs,
- Fix the `typography.css` import in 3 apps,
- Add missing rules which were included by default in v3,
- Run `pnpm dlx @tailwindcss/upgrade` on all apps, which renames a lot
of classes
- Rename all misnamed classes according to
https://tailwindcss.com/docs/upgrade-guide#renamed-utilities in all
apps.

This PR preps the monorepo for a migration to Tailwind v4:
- Bump all Tailwind dependencies and libraries to the latest possible
version, while still compatible with Tailwind 3.
- Cleans up obsolete Tailwind 3 specific options and configs.
- Cleans up unused CSS files and fixes the CSS imports.
- Migrates all `important` uses in `@apply` lines to using the `!`
prefix.
- Move `typography.css` to the `config` package and import it from the
apps.
- Migrated all occurrences of `flex-grow`, `flex-shrink`,
`overflow-clip` and `overflow-ellipsis` since they're deprecated and
will be removed in Tailwind 4.
- Make the default theme object typesafe in the `ui` package.
- Migrate all `bg-opacity`, `border-opacity`, `ring-opacity` and
`divider-opacity` to the new format where they're declared as part of
the property color.
- Bump and unify all imports of `postcss` dependency.
