Accept DB_DATABASE (Coolify convention) in addition to DB_NAME

Coolify auto-injected env vars from an attached Postgres use DB_DATABASE,
but the cotizador code read DB_NAME. Now both are accepted (DB_DATABASE
takes priority) across db.ts, seed.ts, and prisma.config.ts so attaching a
managed Postgres in Coolify Just Works.
