Restrict the fallbacks to the reported delivery failure.

Both catches match every HTTPResponseError with status code 403. A different 403 can trigger the trusted-device fallback or suppress the trusted-device request error. Check error.body for the reported “Could not connect to iCloud” response, and rethrow other 403 responses. Confirm that both endpoints use the same response body before sharing the check.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

at line 32:
Update both HTTPResponseError 403 catch handlers in
GrandSlamTwoFactorAuthenticateOperation to apply their fallback or suppression
only when error.body matches the reported “Could not connect to iCloud”
response; rethrow other 403 errors. Confirm both endpoints return the same
response body before sharing a common check.
