- Fix webhook translation import: read project id, file id and target language from the actual Crowdin payload, with a backward-compatible fallback to the flat keys; guard against unknown job/job item. - Fix WEBXML export: correct plugin constructor signature (was breaking export), make XML element names safe for non-Latin labels, drop deprecated reset() on SimpleXMLElement. - Fix PHP deprecations in createWebhook() (unserialize(NULL) / writing to a boolean).
