chore: Add setup prompt to NotebookNodeTraces

[arthurdedeus]

Problem

When users have not yet sent any LLM generation events, they don't receive clear guidance on how to set up LLM Analytics in person feed.

Part of #40328

Changes

• Added a setup prompt component (LLMAnalyticsSetupPrompt) that displays when no LLM generation events have been detected
• Wrapped the LLM Trace query component in notebook node with this new setup prompt
• Added LLM_ANALYTICS to the ProductKey enum to properly identify this feature
• The setup prompt includes documentation links to guide users on how to instrument their LLM calls

How did you test this code?

• Tested with both states: when LLM generation events exist and when they don't
• Verified the loading state displays correctly while checking event status
• Confirmed the setup prompt appears with proper styling and links to documentation
• Tested that the original query component renders correctly when events exist
