Subject: [PATCH] fix: rebuild assets after content restore to fix ACL

After restoring content tables, deletes stale content-level assets
(articles, categories, modules, contacts, banners) and rebuilds:
- Category nested set tree
- Menu nested set tree
- Asset nested set tree
- Re-creates missing asset entries for articles with asset_id=0

Component and extension-level assets are never touched.
