Claude Code: Fix Cain error field handling - clear stale 'unknown' at startup

- Add missing /app/cain_status.json and /app/data/cain_status.json to cleanup paths
- Always clean stale 'unknown' errors regardless of timestamp (fix: was only cleaning if older)
- Ensure all status file locations are covered for consistent error field handling
