refactor: lift shared rendering methods into _LivePanelBase

_IterationPanel and _IterationSpinner had identical _build_title(),
__rich_console__(), and footer grid logic.  Move these to the base
class so subclasses only override what actually differs (token display,
subtitle, footer summary text).
