fix(#2443): catch fetch() network errors in bindAsyncForms doSubmit

Browse source 
Wrap the fetch() call in a try/catch so network errors (offline, DNS
failure, CORS) surface via themedToast instead of becoming unhandled
promise rejections. The asyncBtn finally() still restores the button
either way — the catch just adds the missing operator feedback.
