When added a new customer that has a domain email address, we shouldn't have to also add them to the member list. If the number of users on the member list is less than the limit, the user should automatically be opted into the member list once a customer is created by the internal admin.

🔍 Problem Statement

When adding a new customer with a domain email address (e.g. user@company.com), Pelcro does not automatically associate them with an existing company account that shares the same domain. Admins must manually link the customer to the company, creating extra steps and risking missed associations.

💡 User Story

As a Pelcro admin, I want new customers with matching domain emails to be automatically linked to the corresponding company account, so that company associations happen without manual intervention.

🎯 Definition of Done (DoD)

A feature is done when:

✔️ Given an existing company account with a known domain, when a new customer is created with an email matching that domain, then the customer is automatically associated with the company account.
