Add notification functionality for new order bookings

- Implemented `onAfterNewBooking` and `notifyNewBooking` methods to handle post-booking notifications.
- Added Slack and SMS notifications for departments upon creating new bookings.
- Enhanced error handling and logging for failed encoding and notification delivery.
- Updated `db_object_t` to JSON encode objects and arrays before database operations.
