Integrate Zod validation in UI screens as POC

Integrating Zod Validation with Schema Generation

Steps to integrate Zod validation:

1. Install Zod and ts-to-zod:
   npm install zod
   npm install -D ts-to-zod

2. Generate Zod schemas from TypeScript types:
   Use ts-to-zod CLI to automatically generate Zod schemas from existing TypeScript interfaces/types.
   Example command:
   npx ts-to-zod packages/auth0-acul-js/interfaces/screens/signup.ts ,
   packages/auth0-acul-js/interfaces/screens/signup.zod.ts

3. Review and customize generated schemas:
   Adjust the generated Zod schemas if needed (e.g., add custom validation messages).

4. Validate form data on submit using generated schemas:
   Use schema.safeParse(formData) to validate data.

5. Prevent form submission on validation failure:
   Block submission until all validations pass.

This draft PR includes the initial setup for client-side validation using Zod schemas generated automatically via ts-to-zod.
