Refine Use Cases and Update Menu Items

We have updated the navigation menu in _includes/navigation.html and the content in platform.html to reflect the new platform features.

Changes made include:

Replaced old menu items with new ones in the navigation.
Updated content sections for platform features including Run AI, Manage API, RAG Data, and Maintain Security.
Made use cases more precise and added numerical data where applicable.

These changes improve the structure, formatting, and conciseness of the use cases content on the website.
