Store the progress setInterval ID in a ref and clear it in a
useEffect cleanup. Previously the interval was stored in a local
variable and only cleared in onSuccess/onError callbacks, leaking
if the component unmounted mid-upload.
Fixes#1090
Fix two timer cleanup bugs in onboarding-tour.tsx:
1. Remove cleanup return from useCallback (only works in useEffect).
Clear retryTimerRef at the start of updateTarget and in a
dedicated useEffect cleanup instead.
2. Track recursive setTimeout calls via startCheckTimerRef so they
are properly cancelled on unmount instead of leaking.
Fixes#1091
