Simplify managing multiple email domains per inbox

Problem
When managing multiple customer email domains (50+) in a single shared inbox, the current UI makes it difficult to view and review all linked email addresses. Similarly, when setting up rules, there's no way to see the complete list of email domains included in each field.

Request
Add a table view to display all linked email addresses and domains for each inbox, making it easier to manage, review, and troubleshoot channel configurations.
