## Context
Initial work for Top for Postgres - adds a "Sessions" section under a
new Observability segment "Database Connections"
NOTE: All the copywriting and naming might change - not sure what's an
ideal title for this
We'll also be iteratively building on top of this UI, adding more
actionable signals instead of just information
Changes are featured flagged, off for public
- This would essentially replace the "View ongoing queries" in the SQL
Editor by providing a dedicated UI
- It checks against `pg_stat_activity` as per the ongoing queries UI
- We'll also subsequently deprecate the "Ongoing queries" UI in the SQL
editor
- Defaults into a "live mode" where the data is refreshed every 3
seconds via long-polling

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.
