Do not use default, instead list all fall-through components explicitly, so if we add a new one, the developer doing that will be forced to consider what to do here. Eliminate the `default` case from the switch in `encryption_file_io_extension::wrap_sink`, and explicitly handle all `component_type` values within the switch statement. fixes: https://github.com/scylladb/scylladb/issues/23724 Closes scylladb/scylladb#24987
