Reminders

Reminders are sent via WP-Cron with two mechanisms:

1. Per-booking events: wp_schedule_single_event() fires at the exact reminder time
2. Hourly sweep: Catches any missed reminders

Both use transient flags (caswell_reminder_sent_{id}) to prevent double-sends.

Configure in Settings → Scheduling:

• Reminder Timing: Hours before appointment (default: 24)
• Enable Email Reminders: Toggle
• Enable SMS Reminders: Toggle
