fix: copy prisma.config.ts into runner so db push can find datasource URL

Without prisma.config.ts in the runner stage, prisma db push has no
datasource URL (schema.prisma no longer carries url in Prisma 7) and
silently skips creating the database. Also add set -e to the entrypoint
so any db push failure is visible in logs and stops the container.
