Add tests for react-styled package

[alikhere]

Description:
packages/react-styled has no test script and no tests. The package currently exposes one component: StorachaAuth (and its subcomponents: Form, EmailInput, CancelButton, Submitted, Ensurer). Tests should cover the styled StorachaAuth: that it renders without error, that the form and Ensurer render with the expected labels/placeholders, and that exports work when used with Provider from the headless package.

Expected outcome:

• A test script in packages/react-styled/package.json (e.g. vitest run), plus vitest and testing-library as devDependencies if not already present.
• A test file (e.g. packages/react-styled/test/StorachaAuth.spec.tsx) with at least: rendering StorachaAuth.Form and StorachaAuth.Ensurer (with Provider from headless), and asserting on visible text (e.g. "Email", "Authorize", "Verify your email").
