fix(journey): keep the card-click ref in JourneyMap and type the pin event test

The marker effect reads the card handler through the component's own ref
again, so exhaustive-deps sees a ref it knows, and the card hook takes it
alongside the map's other refs. The pin event assertion types the mock
calls it maps under strict mode.
