fix: correct TypeScript test types for CI compatibility

Fix type errors in client.test.ts that caused CI typecheck to fail:
- Use vi.fn<typeof fetch>() for proper mock typing
- Cast headers to Record<string, string> for type safety
- Remove FormData.entries() usage (not in Node.js types)
- Use formData.get('token') instead for null check
