`echoDeleteData` Replaces The Three ECHO Delete Mutations

echoDeleteData deletes ECHO order history, shipment history, or inventory snapshot records. Each request selects one dataset and either a list of IDs or the same filters the list queries accept. The three earlier delete mutations, one per dataset, are removed. Update any caller to the new name.

Deleting by IDs finishes in the request and returns deletedCount. Deleting by filters runs in the background across all pages and returns a processId. Filtered deletion skips records changed after the request. The mutation requires the new echo:delete_data permission, which company operators and operations integrations do not hold. Records created automatically are never deleted.
