refactor: enhance CallToAction cyan glow visibility and add overflow-hidden across all pages

- Increased cyan radial glow fillOpacity from 0.2 to 0.4 for better visibility
- Added overflow-hidden class to main container div to prevent glow overflow
- Applied changes consistently across agents, cloud, compute, gpu, network, nodes, pods, and storage CallToAction components
