Create audit task in database from channel mention

Uncaptured channel audit mentions leave reviews unassigned and dates unclear. Creates task records with assignee and due date so audits are scheduled and visible same day.

Overview

When audit requests appear in chat they often go unassigned and miss review windows; this ties those mentions to tracked task records so operations coordinators always have an owner and a date. The integration schedules and surfaces audits same day, reducing missed reviews and manual follow-up.
