Log the failed request in the all-domains error path

The FluxC implementation logged `result.error.message`; the wordpress-rs
version logged only a constant string, leaving no status code, URL, or
reason to triage a failure with. Use `toLogErrorString()`, which formats
each `WpRequestResult` failure variant for diagnostics.
