Combined Comment Reply + DM Automation

Allow users to configure a single keyword-based automation that both replies publicly to the triggering comment and sends a separate private DM containing a message, link, free resource, or media.

This will eliminate the need to create separate automations for the same campaign, simplify setup, and create a more professional experience. Users should be able to customize the public comment reply and the DM content independently within the same automation, while maintaining existing variation behavior and Meta messaging compliance.
