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.

Resolves FE-3077
Related discussion: https://github.com/orgs/supabase/discussions/45233
Verifying the correctness of your RLS policies set up has always been a
gap, as highlighted by a number of GitHub discussions like
[here](https://github.com/orgs/supabase/discussions/12269) and
[here](https://github.com/orgs/supabase/discussions/14401). As such,
we're piloting a dedicated UI for RLS testing (using role impersonation
as the base), in which you'll be able to
- Run a SQL query as a user (not logged in / logged in - this is the
role impersonation part)
- See which RLS policies are being evaluated as part of the query
- And hopefully be able to debug which policies are not set up correctly
Changes are currently set as a feature preview - and we'll iterate as we
get feedback from everyone 🙂🙏
