i18n+tests: add list_item_numbered, list_footer_numbered, out_of_range for 15 locales

The numbered /resume feature added new i18n keys to en.yaml; the catalog parity
tests require every locale to carry matching keys and placeholders, so add
translations to all 15 supported locales.

Also unblock tests/cli/test_cli_resume_command.py:
- _make_cli stub now sets self.resume_display = 'minimal' since
  _handle_resume_command (post-#31695) calls _display_resumed_history.
- mock_db.resolve_resume_session_id returns the input id (no compression
  chain) so HERMES_SESSION_ID is set to a real string, not a MagicMock.
