Fix: check isinstance(_raw, (classmethod, staticmethod)) to distinguish both descriptor types from a plain function; for either, call _original(db_name) since the descriptor protocol already resolves the callable correctly. Only plain functions (Django 4.x) need _original(cls, db_name). Also fix MySQL sequence_reset: `or 0` on empty tables sets AUTO_INCREMENT=0 which MySQL 8 ignores (counter stays at previous value).
