[FEAT] Replace banner image with hot products carousel

[BenGWeeks]

Problem

The current nostrich banner image at the top of the marketplace, while visually appealing, takes up valuable screen real estate that could be used to showcase products.

Proposed Solution

Replace the static banner image with a product carousel featuring "hot" or featured products:

Features

• Rotating carousel of featured/trending products
• Start with LNbits official products as defaults
• Could include:
  • Best sellers
  • New arrivals
  • Featured merchants' products
  • Seasonal/promotional items

Benefits

• Better use of prime screen real estate
• Immediate product discovery for new visitors
• Increased engagement with actual marketplace content
• More useful first impression than a static image

Implementation Ideas

• Use Quasar's carousel component
• Auto-rotate with manual navigation
• Link directly to product pages
• Could be curated or algorithm-driven (most viewed, recently added, etc.)
