Add AI Chatbot page with OpenAI integration

Introduced a new /ai/chatbot page featuring a chat UI for interacting with an AI assistant powered by OpenAI. Integrated the OpenAI .NET SDK and added configuration for API keys and model selection in appsettings.json. Updated the navigation menu to include the Chatbot, and added the OpenAI NuGet package dependency. The chat interface supports avatars, message bubbles, copy-to-clipboard, auto-scroll, and error handling.
