Add contact note when presentation email is opened

You get email-open webhooks with no linked CRM contact, so reps lack context for outreach. Attach a read note to the contact so reps can follow up same day.

Overview

Inbound read events often arrive without CRM context, leaving reps unaware of engagement. This flow writes a read note directly to the contact timeline so reps see opens and can act the same day for faster follow-up.
