feat(app): Support Prisma Next branch database setup

[luanvdw]

Overview

This extends branch database setup during app deploy so Prisma Next apps get the same database creation and schema setup path as Prisma ~7 apps. The deploy workflow can now apply schema from local code without adding a separate database command surface.

Changes

• packages/cli/src/lib/app/branch-database.ts now scans for prisma-next.config.* alongside schema.prisma, classifies supported and unsupported database targets, and prefers Prisma Next configs when both sources exist.
• Prisma Next setup runs npx --no-install prisma-next contract emit --config <config> followed by npx --no-install prisma-next db init --config <config> --db <database-url>. Prisma ORM keeps migrate deploy when migrations exist and uses db push otherwise.
• packages/cli/src/lib/app/branch-database-deploy.ts rejects explicit --db for known non-Postgres Prisma sources and suppresses automatic prompting for those unsupported sources. Schema setup errors now return recovery commands for the selected source.
• packages/cli/src/types/app.ts and packages/cli/src/presenters/app.ts carry and render the schema source/command so deploy output and JSON can distinguish Prisma ORM from Prisma Next.
• packages/cli/tests/app-branch-database.test.ts covers the new command sequence, Prisma Next deploy setup, source precedence, unsupported targets, and the Prisma 7 db push command shape.
• docs/product/command-spec.md, docs/product/resource-model.md, and docs/product/error-conventions.md describe the expanded schema-source contract.

Why

Prisma Next does not use schema.prisma as the deploy-time schema artifact, so the existing branch DB setup skipped schema application for those apps. Keeping this inside app deploy --db preserves the current CLI/CI surface while letting the implementation choose the right local schema source. Known non-Postgres targets are rejected before database creation because this workflow creates Prisma Postgres databases and should not silently wire an incompatible branch database.
