feat: add cloud services dropdown menu in header

- Replaced individual cloud service pages with CallToAction components for Compute, Storage and GPU
- Added dropdown menu in header to consolidate cloud service navigation options
- Removed redundant page components (Compute.tsx, Storage.tsx, Gpu.tsx) that shared identical layouts
- Updated route components to use new CallToAction components
- Added ChevronDownIcon to visually indicate dropdown functionality
