feat(DATAGO-104907): Suggest potential things I can do when launching a new chat

[amir-ghasemi]

This pull request introduces a new "starter cards" feature to the chat interface, providing users with intelligent, LLM-generated (or default) suggestions to help them start a conversation. The implementation includes backend API integration, UI components for displaying and interacting with starter cards, and logic to handle the empty chat state with a personalized greeting. Additionally, tests and exports are updated to support the new feature.

Starter Cards Feature Implementation

• Added a new API layer for fetching LLM-generated starter card suggestions, including query keys, service functions, and a custom React Query hook (useStarterSuggestions). [1] [2] [3] [4]
• Created the ChatStarterCards component, which displays a set of suggestion cards (either LLM-generated or default), handles user interactions (expanding cards, selecting options), and emits events to trigger chat input submission.
• Exported ChatStarterCards from the chat components index for use elsewhere in the app.

Chat Page Integration and UX Enhancements

• Integrated ChatStarterCards into the ChatPage component, displaying it in the empty chat state alongside a personalized greeting based on the user's name or email. Added logic to determine when the chat is empty and to handle starter card option clicks by dispatching a custom event. [1] [2] [3] [4]
• Updated ChatInputArea to listen for the starter card submit event, automatically submitting the selected prompt as a user message.

Testing and Mocks

• Updated chat page tests to mock the authentication context and the new ChatStarterCards component, ensuring test coverage for the new feature. [1] [2]
