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 pull request migrates all SCSS stylesheets in the `apps/studio` and
`apps/docs` projects to CSS, updates import paths accordingly, and
consolidates PostCSS configuration to use a shared config. The migration
includes renaming files, updating import statements, converting SCSS
comments to CSS comments, and removing redundant or legacy configuration
files. The changes improve maintainability and consistency across the
codebase.
**Migration from SCSS to CSS:**
* All SCSS stylesheets in `apps/studio/styles` and `apps/docs/styles`
have been renamed to `.css`, and their contents updated by converting
SCSS comments (`// ...`) to CSS comments (`/* ... */`). All relevant
import statements in the app entry points have been updated to reference
the new `.css` files.
**PostCSS configuration consolidation:**
* The separate `postcss.config.cjs` files in `apps/design-system`,
`apps/learn`, and `apps/studio` now all import from a shared
`config/postcss.config`, ensuring consistent PostCSS setup across
projects. The legacy `postcss.config.js` in `apps/studio` has been
removed.
**Code and style consistency improvements:**
* All instances of the SCSS-specific `#{!important}` in Tailwind
`@apply` rules have been replaced with the standard CSS `!important`
syntax.
* Minor fixes and comment updates were made throughout the stylesheets
to improve readability and maintainability, such as moving or clarifying
TODOs and notes.
These changes streamline the styling approach, reduce build complexity,
and make it easier to maintain and scale the design system and
documentation styles.
