fix(carousel): add carouselCardType HSCROLL_CARDS and remove viewOnceMessage

Two changes to fix carousel rendering on WhatsApp Web/Desktop:

1. Added carouselCardType: 1 (HSCROLL_CARDS) to carouselMessage - this
   proto field tells the client how to render carousel cards. Without it,
   Web/Desktop doesn't know to render horizontal scrollable cards.

2. Removed viewOnceMessage wrapper - confirmed it causes error 479
   rejection from linked devices (Web/Desktop). Carousel works as
   direct interactiveMessage on phone; carouselCardType should fix Web.
