Migrate twenty-front package from Zod v3 to v4

[abdulrahmancodes]

The backend has been upgraded to Zod v4.1.9 to support AI SDK v5, creating a version mismatch with the frontend, which is still using Zod v3.23.8. This migration will ensure consistency across the codebase and allow us to leverage Zod v4's performance improvements and new features.
