feat: add back grok 3 mini and API key management functionality

- Integrated the XAI provider into the application, allowing for model interactions.
- Implemented an API Key Manager component for managing API keys for OpenAI, Anthropic, Groq, and XAI.
- Updated the Chat Sidebar to include an option for accessing the API Key Manager.
- Enhanced the providers.ts file to utilize the new XAI client and manage API keys securely.
