Brevo + Mailbox Power Integration

Keep Brevo and Mailbox Power aligned: when communication events happen in one, update the other automatically.

Example: when Brevo's "Watch Activity Logs" fires, WEXTL can "Add a Contact to a Group" in Mailbox Power. Brevo has 21 triggers (including Watch Activity Logs, Watch Email Campaigns, and Watch Email Events); Mailbox Power has 14 actions (including Add a Contact to a Group, Add a Contact to Automation, and Create a Contact).
