feat : "Meilleures audiences" + admin/stats pages via flux RSS XML (v1.6.6)

- post_list.php : section AJAX qui lit /trending?period=1h en XML (DOMParser) — plus de rendu PHP
- admin_stats.php : colonne "Pages les plus visitées" chargée en AJAX depuis /trending?period=14d XML
- index.php/stats : suppression de topGrouped pour /post/ ; seuls /book/ et ASN restent côté serveur
