fix: rewrite index.html from scratch - fix completely broken product grid

The previous index.html had corrupted HTML structure where:
- EoSim card was missing its opening tags entirely (only orphaned badges remained)
- EoStudio card was nested inside a hw-grid div
- Desktop/TV/Laptop/Tablet/Kiosk items were injected inside card elements
- Multiple unclosed divs caused entire page layout to collapse

This commit rewrites index.html cleanly with:
- All 10 product cards properly structured and closed
- Each card: card-icon, h3, p, card-tags, card-buttons, proper closing divs
- EoSim card fully present with Simulator/52 Platforms/Cluster badges
- EoStudio card as standalone card with Design/AI Tutor/10 Editors badges
- New eos-platform card for Desktop/TV/Laptop/Tablet/Kiosk form factors
- Clean Architecture, Hardware, and Quick Start sections
- Proper navbar with hamburger menu for mobile
