How muting/unmuting changes appear in scheduled SMS messages

When muting/unmuting, related registrations that have“scheduled_tasks” (SMS messages which are scheduled to be sent) are updated
The action of muting will update all “scheduled_tasks” which are in “scheduled” or “pending” state, setting their state to “muted”
The action of unmuting will update all present or future “muted” “scheduled_tasks”, setting their state to “scheduled” (messages with a due date in the past will remain “muted”).
