/**
* admin/statistics.php
*
* Statistiques par pays, operateur, technologie et bande. Page en
* lecture seule : aucune ecriture, aucune action sensible. Uniquement
* des agregations SQL via requetes preparees.
*
* CORRIGE (20/09/2026, suite a erreur 500 en usage reel) : cette page
* utilisait des noms de colonnes inexistants dans le schema reel
* (o.name, c.technology), ecrits avant que le schema definitif
* (install_full_schema.sql) ne soit connu. Alignee maintenant sur les
* vraies colonnes :
* - operators.brand (pas "name")
* - cells.tech (pas "technology")
* Ajout egalement du require_once _nav.php qui manquait, provoquant
* une erreur fatale "Call to undefined function render_admin_nav()".
