Requires the AccountAdmin policy and the database_connector feature.

Backfills the affiliate's external mirror database. The dataType selects what is reloaded:
clicks (default), conversions or pageviews reload the corresponding events
over the fromDate..toDate window, while dimensions re-runs the dimension
merge (the date range is ignored for that mode). Runs asynchronously; the response payload
carries an executionId for progress tracking. The affiliateId in the body is
ignored — it is resolved from the connector identified by the route.
