fix(cli): surface recent sessions inside /history and /resume

When /history is used in an empty chat, show a table of recent
resumable sessions instead of a dead-end message. When /resume is
called with no argument, show the same table with resume guidance.

- Add _list_recent_sessions() and _show_recent_sessions() to HermesCLI
- Remove redundant exclude_sources (already filtered by source='cli')
- Center the table header properly

Cherry-picked from PR #4448.
