Update website images to modern, contemporary design style

[SammyOina]

Is your feature request related to a problem? Please describe.

The current website uses screenshots and images that are heavily documentation-focused and centered towards technical dashboards (e.g., prism-ui.png, policies.png, backends.png, logs.png, runtimes.png). These images feel more aligned with product documentation rather than marketing materials that inspire confidence and excitement about the platform. A modern, contemporary visual style would better convey the sophistication and trustworthiness of Prism AI as a confidential computing platform.

Describe the feature you are requesting, as well as the possible use case(s) for it.

Replace the current dashboard/documentation-style images in the DetailedFeatures.tsx component with modern, visually appealing graphics that:

• Use contemporary design aesthetics (clean, minimalist, or illustrative styles)
• Better represent the business value and real-world applications of Prism AI
• Include custom illustrations, 3D renderings, or abstract representations of security concepts
• Maintain visual hierarchy and consistency with the brand guidelines
• Improve the overall marketing impact and user engagement on the landing page

This will enhance the perceived quality of the platform and better attract potential users and partners.

Indicate the importance of this feature to you.
