Add Err() method to storage.Iterator interface and implement it on all backends (LevelDB, PostgreSQL, in-memory). Update kvtpl.KVIterator.Err() to fall through to the underlying iterator's error. Check Err() after every iteration loop across kvtpl and usecase layers to surface I/O failures and rate-limit errors instead of returning truncated data.
