-- Clear stale tracker initiator attribution that wrongly pointed at the
-- @probo/cookie-banner SDK bundle. A pre-fix SDK bug walked its own bundle
-- frame when computing the initiator, so cookies/storage written by third
-- parties (or by malware / browser extensions) were attributed to
-- cookie-banner.iife.js. The SDK now excludes its own bundle, but the report
-- upsert keeps the existing value on re-detection
-- (initiator_url = COALESCE(new, old)), so rows whose corrected initiator is
-- NULL would otherwise keep the stale value forever. NULL them here; genuine
-- third-party rows repopulate with the correct initiator on next detection.
