refactor: simplify navigation structure and update homepage content

- Removed Cloud dropdown menu and flattened navigation to direct links (Network, Cloud, Pods, Agents, Node)
- Reordered navigation items for better flow and renamed "Nodes" to "Node" for consistency
- Updated homepage hero and CTA sections with clearer messaging focused on digital sovereignty and infrastructure control
- Added new bento grid images for visual refresh
