- Add EPYC Cluster card to landing page (first position, purple/pink gradient)
- Add back button to cluster page (animated left arrow, links to dashboard)
- Update landing page grid layout (lg:grid-cols-3 xl:grid-cols-4 for 7 cards)
- Complete bidirectional navigation: dashboard ↔ cluster monitoring
Navigation features:
- Cluster card: 🖥️ icon, "Monitor distributed parameter exploration" description
- Back button: Animated hover effect (arrow slides left, color transitions)
- Responsive grid: 2 cols (mobile), 3 cols (tablet), 4 cols (desktop)
- Consistent styling with existing navigation cards
