Subject: [PATCH] fix: inline carousel handler for WhatsApp Web rendering

Replace generateCarouselMessage() call with inline handler that builds
interactiveMessage directly. Validated working on Android, iOS, and Web.

Key rules from Frida captures:
- Direct interactiveMessage at root (field 45), NO viewOnceMessage wrapper
- NO messageContextInfo (breaks iOS)
- NO biz/bot stanza nodes
- messageVersion: 1, subtitle = footer text
- Cards must have images for Android rendering
