Address code review feedback on logging configuration

- Use exact type check (type(h) is logging.StreamHandler) instead of isinstance
  to avoid confusion with FileHandler subclass
- Catch specific exceptions (IOError, OSError, PermissionError) instead of
  bare Exception when creating FileHandler
- Kept logging.ERROR as default to maintain consistency with existing behavior
