feat(www): clarify database-only positioning on the database page (#50667)

## Summary

Clarifies on the database product page that a Supabase project can be
used as a standalone Postgres database, and mirrors the change in the
page's markdown version (`/database.md`).

Ref: GROWTH-1191

## Changes

- **Hero and page metadata**: adds "Use it on its own, or with the rest
of the Supabase platform."
- **Features section**: intro reframed around the database. The "Just
Postgres" card heading adds "standalone".
- **`content/md/database.md`**: same sentence in the tagline. New short
"Use it as a standalone database" section covering connecting, pooling,
pricing, and Free plan pausing. Client libraries marked optional. Pooler
naming updated to Supavisor. Links added for the connection guide and
`pricing.md`.

## Notes

- Pricing figures in the markdown mirror `packages/shared-data/plans.ts`
and are static here.
- The pausing statement matches
`docs/guides/platform/free-project-pausing`.

 Supabase Database gives you a full Postgres database with no compromises. It is not a Postgres-compatible alternative or a shared cluster: every project gets its own dedicated Postgres instance that you can connect to directly with any Postgres client.
 
+## Use it as a standalone database
+
+You do not need any other Supabase product to use the database. Auth, Storage, Realtime, and Edge Functions are included in every project but optional. Unused products cost nothing.

+- **Connect with anything**: standard Postgres connection string. Works with psql, Prisma, Drizzle, or any Postgres client or ORM.
+- **Connection pooling**: Supavisor, with session and transaction modes.
+- **Pricing**: the Free plan includes a 500 MB database. The Pro plan starts at $25/month and includes one Micro compute instance and 8 GB of disk. Current pricing: https://supabase.com/pricing.md
+- **Pausing**: Free plan projects pause after 7 days of low activity. Paid plan projects do not pause.
