 * Container entrypoint: apply Prisma migrations, then start Next server.
 *
 * Why:
 * - In real deployments you want schema changes applied automatically per deploy.
 * - `prisma migrate deploy` is safe to run multiple times (idempotent).
 *
 * Controls:
 * - Set `SKIP_PRISMA_MIGRATE=true` to skip migrations (emergency / debugging).
