- All data widgets (tables and cards) now use the useIsHoliday hook. - An informational alert is displayed on holidays, without hiding the last available data. - Unifies loading state logic to wait for both data and holiday status, preventing race conditions. - Ensures a consistent and robust user experience across all components."
