fix(listes): exclure les pages-supports de templates des listes utilisateur

Les pages-supports créées par TemplateService._create_holder (une par
template, search_excluded=1, « masquées, jamais listées ») n'étaient
exclues d'aucune liste : semées à l'init avec updated_at = now (99 sur
une base fraîche), elles occupaient toutes les places des listes
triées par récence (LIMIT 50/20/8) devant les vraies pages — cause
racine de 7 échecs CI (library recents/private/workspace, sidebar
recents, projets builtin, mentions agent), dont l'instabilité du test
provenance (égalité de seconde avec le seed).

Filtre COALESCE(search_excluded, 0) = 0 ajouté : onglets bibliothèque
(meetings, recents, favorites, shared, published, private, workspace),
sidebar Recents, projets builtin, scans de pages des mentions agent.
