toClient() never returned the message body (html/text for email,
message for WhatsApp), so "Manage scheduled" showed nothing to view
or edit even though the content existed in storage. Editing a
scheduled WhatsApp message also saved to the wrong payload field
(text instead of message), silently discarding the edit.

The scheduled-job store never persisted the channel field, so the
send worker always fell through to its email branch regardless of
what was requested. Also purges sent jobs 24h after sending instead
of keeping them forever, and surfaces who each scheduled job will go
to in the admin "manage scheduled" lists (now correctly filtered per
channel too).
