Deactive user account.
This custom code( Snippet code ) enables user account deactivation. It prevents direct access for security and provides the following functionalities:

1. User Account Deactivation: Logged-in users, except administrators, can deactivate their accounts through a generated link. This process includes a security check (nonce) and a confirmation step.
2. Admin-Led Reactivation: Administrators can reactivate user accounts.
3. User Interface Enhancements: Adds new columns in the admin area to show user account statuses and provide reactivation links.
4. Login Restriction: Prevents deactivated users from logging in.
WordPress Integration: Uses WordPress hooks for seamless integration with the user management system.

Shortcode: [custom_deactive]
