/**
 * SEOPress PRO — Last-resort post ID resolver for Search Console rows via Polylang.
 *
 * When url_to_postid() returns 0 (typically because the URL belongs to a translation
 * whose permalink is owned by the multilingual plugin), this snippet asks Polylang
 * to resolve the URL using its own router. The resolved post then receives the
 * GSC metrics (clicks, impressions, CTR, position) on each daily sync.
 *
 * Hook: seopress_search_console_match_post_id
 * Plugin: SEOPress PRO 9.9+
 * Requires: Polylang (or Polylang Pro)
