Subject: [PATCH] fix(frontend): guard response.error.includes against
 non-string error values

If the API returns a non-string error (e.g. numeric HTTP status code),
calling .includes() directly on it throws "N.includes is not a function".
Convert to string via JSON.stringify first.

Fixes save button crash on rules/new page.
