fix: reminders include contacted bookings, confirmation details persist after status revert

- Reminders query now includes 'contacted' group bookings with confirmed_date,
  preventing people from being forgotten when admin hasn't clicked "Подтвердить"
- Confirmation details (group, date) remain visible regardless of booking status,
  so "Вернуть" no longer hides previously entered info
