fix: Disable follow-up suggestions while chat response is loading

[Prasanjeet-Microsoft]

Purpose

• This PR improves the chat room UX by disabling follow-up suggestions while the chat API is responding.
  The component already tracked isLoading, but it wasn't applied to the follow-up question click handlers.
  Now, follow-up suggestions are disabled during loading, preventing duplicate API calls and improving flow control

Does this introduce a breaking change?

• Yes
• No

Golden Path Validation

• I have tested the primary workflows (the "golden path") to ensure they function correctly without errors.

Deployment Validation

• I have validated the deployment process successfully and all services are running as expected with this change.

What to Check

Verify that the following are valid:

• Follow-up questions are clickable after a response is received.
• Follow-up suggestions are disabled only during loading.
• No extra states or incorrect disabling happens.
• Full chat flow (user message → response → follow-up) works correctly.
