fix: reduce timeout detection to 5 seconds for faster user feedback

- Changed from 30s to 5s timeout for amber indicator
- Users see 502 errors almost instantly, 30s was too long
- 5 seconds is enough to avoid false positives during normal load
- But quick enough to guide users when there's an actual 502
