Fix test:view React.act is not a function errors in Copilot CLI

Copilot CLI runs shell commands with `NODE_ENV=production` in the environment,
which leads to errors when validating its changes against the view tests,
because the `React.act` function (used by `@testing-library/react` via
`react-dom/test-utils`) is only exported when `NODE_ENV != production`.
