Refactor to use table::add_new_sstable() and add test

- Add table::add_new_sstable() method that wraps error handling
- Update streaming/consumer.cc to use new method
- Update streaming/stream_blob.cc to use new method
- Add test_add_new_sstable_cleanup_on_failure test to verify cleanup

Addresses feedback from @tgrabiec to extract common logic into a reusable method.
