Add signed waivers to guest messaging and notification list

Uncaptured waiver signups leave your activity teams without contacts for day-of alerts. This adds signers to your messaging list so coordinators can send confirmations and reminders same day.

Overview

Waivers without captured contacts create last-minute scramble and missed safety notices for on-site teams. This flow captures waiver signers and pushes them into your messaging list so coordinators can send confirmations and safety reminders the same day.
