Make cursor land on First Name (as opposed to email address)

🔍 Problem Statement

When the registration form includes first and last name fields, the cursor automatically focuses on the email field instead of the first name field, which is unexpected and creates a confusing user experience.

💡 User Story

As a user, I want the cursor to land on the first name field when it is present in the registration form, so that I can start filling out the form in a natural and logical order.

🎯 Definition of Done

1. Given the registration form includes first and last name fields, when the form loads, then the cursor should automatically focus on the first name field.

2. If the first/last name fields are not enabled, the cursor should default to the email field.

3. This change impacts the UI (registration form field focus behavior).

4. The focus order should follow a logical top-to-bottom flow of fields.
