feat(ecommerce): cuentas de cliente reales (registro + login)

Conecta el dialogo 'Tu cuenta ARI' (antes solo ofrecia WhatsApp) al
Store API real de Medusa. Flujo verificado en vivo con un cliente de
prueba real antes de escribir el codigo: registro -> crear customer
-> login -> /store/customers/me, todo confirmado funcionando.

Detalle no documentado que se confirmo en vivo: el token que devuelve
/auth/customer/emailpass/register sirve para crear el customer via
POST /store/customers, pero no queda como sesion real -- hay que
loguear de nuevo (/auth/customer/emailpass) para obtener el token de
sesion. Mensajes de error tambien verificados: correo repetido -> 401
'Identity with email already exists'; credenciales invalidas -> 401
'Invalid email or password'.

Mismo patron arquitectonico que el carrito real (ADR 0009): rutas
puente /api/customer/* (MEDUSA_BACKEND_URL es DNS interno, no resuelve
desde el navegador), store de Zustand con sesion persistida y
resincronizada contra el servidor al rehidratar. WhatsApp se mantiene
como opcion secundaria, ya no es la unica salida.
