chore: release v1.0.210 [skip ci]

Siguiente corte tras el carrito real: pagina /checkout de 3 pasos
(direccion -> envio -> confirmar) contra el Store API real, usando la
shipping option que ya se verifico en produccion. Endpoints nuevos
(setShippingAddress, getShippingOptions, addShippingMethod) probados
en vivo con un carrito de prueba real antes de escribir el codigo --
direccion, opciones de envio y total ya confirmados correctos
(80.000 + 5.000 = 95.000).

El pago (PayU custom) sigue sin existir, asi que el ultimo paso sigue
siendo WhatsApp -- pero ahora el mensaje incluye direccion, metodo de
envio y total real en vez de solo la lista de productos. El boton del
CartDrawer pasa de abrir WhatsApp directo a llevar a /checkout.
