fix: add fs-zone-card to driver components so font size settings apply

Driver components (DriverDeliveryPlanner, DriverShipmentPanel,
DriverDeliveryDetail) were missing fs-zone-card class wrappers.
Font size settings from SettingsPage saved to localStorage correctly
but never applied to driver UI because fontSettings.css only
overrides Tailwind text-* classes inside .fs-zone-* wrappers.
