Webhook — Availability Notify
Inbound webhook for real-time availability updates in the OCTO AvailabilityNotify format.
Send this when a single availability slot changes (status, capacity, vacancies) to avoid triggering
a full sync. Requires x-webhook-secret header.
If the target activity or variation cannot be matched locally, Seyaha falls back to triggering a full sync in the background.
