fix(orchestrator): copy apps/api/package.json into Dockerfile for prisma generate

Prisma generate needs a package.json in the inferred project root to identify
the workspace. Without it, Prisma tries to auto-install and fails.

Copying apps/api/package.json alongside the schema file provides the required
project root marker.
