feat(v1.3.0): Step 2 — DB tables collections, collection_pages, collection_views

- Ajout des 3 nouvelles tables pour le Database Concept
- collections: base de données abstraite, indépendante de Gitea
- collection_pages: pages génériques avec parent_id et property_values_json
- collection_views: vues configurables par collection
- Mise à jour test_db_tables_exist pour inclure les nouvelles tables
- 28/28 tests passent
