Domain-Level Team Member Access

Add the ability to assign team members with domain-specific access permissions. Users managing multiple domains need to grant collaborators access to view logs and manage suppressions for only their respective domains, rather than having full account access. Use Case: Customer currently manages 7+ domains and wants to give each domain owner/administrator access to view their own domain's email logs and suppression lists without exposing data from other domains. Proposed Solution: Add team member management at the domain level Implement domain-scoped permissions Restrict team members to only see data for their assigned domain(s)
