fix: carousel renders on WhatsApp Web without F5

Two fixes:
1. Stanza type="media" for carousel messages — WhatsApp Web needs this
   to render carousel in real-time. Without it, only shows header until
   page refresh (F5).
2. Fix jimp detection: typeof Jimp === 'function' (not just 'object')
   so jpegThumbnail is generated for card images.
