 * `CalendarPrevYearGroupButton` is a control button used within the Calendar
 * to navigate to the previous group of years.
 *
 * The button is context-aware and only becomes interactive when the calendar
 * is in `year` picker mode. In all other picker modes, the button is disabled
 * and visually hidden via a `data-visible` attribute.
 *
 * Internally, it composes `CalendarBaseControlIconButton` and merges an optional
 * external `onClick` handler with the calendar context action responsible for
 * switching to the previous year group.
