This PR fixes a bug where a user might choose `classic-dark` as a theme
in `studio` but then `docs` and `marketing` apps will look weird.
To test:
- Change the localStorage value of `theme` to `classic-dark`
- Open `www` and `docs` apps, they should look ok

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.

This PR moves several components which rely on `next` out of the `ui`
package to the `ui-patterns` package.
`ui-patterns` package is intented to be imported with specific imports
so it's ok if there are components reliant on `next` in there.
The `SonnerToaster` component has removed its dependency by requiring a
prop for `theme`.
