Reserved/private SQL files (sqlpage/ prefix, dotfiles, .. traversal,
absolute paths) became directly routable over HTTP while their parsed
form was fresh in sql_file_cache. A trusted page loading such a file via
sqlpage.run_sql(...) loads it with privilege and caches it; a later
direct unprivileged request hit the fresh cache entry before the path
guard ran, returning 200 and executing the private SQL instead of 403.
The unprivileged path validation is extracted into
filesystem::validate_unprivileged_path and now enforced before
consulting the cache in both HTTP routing (AppFileStore::contains) and
the unprivileged FileCache::get_with_privilege path.
