Refactor booking update logic so that updates without feedback are sent to the new async update bookings endpoint, significantly increasing the speed of the integration.
Refactor error messages, the integration should now send fewer - more useful errors.
Added payload validation so the integration will no longer attempt to send payloads where contact details are not available.
Remove throttling - no longer necessary now all payloads are being sent via async routes. Reducing the overall run time of daily syncs.
