Subject: [PATCH] WebUI: Continue polling after network error

These `fetch` calls properly handle 4xx and 5xx errors, but don't handle network errors. In all cases, I've used the same logic as the `!response.ok` branch of each individual fetch function. This should ensure consistent behavior.

PR #23164.
