Greptile Summary

This PR activates an announcement banner to promote the launch of Helicone AI Gateway with passthrough billing functionality. The changes involve two straightforward modifications:

1. Activating the Banner Component: The PR uncomments the Banner component import and render call in bifrost/app/components/Layout.tsx, making it visible across all pages in the application. The banner is positioned at the top of the layout, before the navigation bar, ensuring maximum visibility.

2. Updating Banner Content: The Banner component in bifrost/components/home/Banner.tsx is updated with new marketing content. The link now points to a blog post about the PTB (passthrough billing) gateway launch instead of the previous beta announcement. The text emphasizes the new cloud availability and passthrough billing feature with "Helicone AI Gateway, now on the cloud with passthrough billing. Access 100+ models with 1 API." The background color is also changed from bg-blue-600 to bg-sky-500.

This appears to be a coordinated marketing effort to announce a significant product milestone - the full launch of their AI Gateway with passthrough billing capabilities, transitioning from what was previously a beta offering. The banner serves as a prominent call-to-action driving users to learn more about this new feature through the linked blog post.

Confidence score: 5/5

• This PR is safe to merge with minimal risk as it only involves simple UI updates to announce a product launch
• Score reflects straightforward changes with no complex logic, database operations, or breaking modifications
• No files require special attention as both changes are simple text/styling updates to existing components
