Removes the SQL Editor Pretty Explain feature — the Explain tab, the Run
EXPLAIN ANALYZE action + shortcut, and its dead plumbing. It's been
gated off behind the `DisablePrettyExplainOnSqlEditor` kill switch for
weeks with no usage or complaints.
`ExplainVisualizer` / `isExplainQuery` are kept — they're used
independently by Query Insights, Query Performance, and the EditorPanel
quick-runner. Manually-run `EXPLAIN` queries still render as raw rows in
the Results tab.
Typecheck, lint, and all affected unit tests pass.
Closes FE-3930

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.
