Autocalls AI + seven.io Integration

Keep Autocalls AI and seven.io aligned: when communication events happen in one, update the other automatically.

Example: when Autocalls AI's "Watch Calls" fires, WEXTL can "Create Contact" in seven.io. Autocalls AI has 3 triggers (including Watch Calls, Watch Inbound Events, and Watch Leads); seven.io has 47 actions (including Create Contact, Create Group, and Create Subaccount).
