refactor(cli): move the output-history row helpers out of the cli facade (#95375)

_output_history_lines / _output_history_rows are new in this PR; they belong with the
rest of the history rendering in hermes_cli/cli_render.py, not appended to cli.py.
cli.py imports them for _replay_output_history; the terminal mixin imports them from
cli_render directly.
