The early termination issue was caused by the page navigating away before
the send-notification function call could complete. Changed from fire-and-forget
to awaiting the email send result before redirecting.
Changes:
- Checkout.tsx: Changed send-notification call to use await instead of .then()/.catch()
- Now waits for email send to complete before navigating to order detail page
- Email failures are caught in try/catch but navigation still proceeds
Technical details:
- Browser was terminating pending requests when navigate() was called immediately
- Early termination: isolate warning indicated function was being killed mid-execution
- Awaiting the function call ensures it completes before page navigation
