[UI]: Improvements: Auto-Scroll, Dynamic Input, and Click-Outside Sidebar Close

[echo-64]

Feedback Summary

There are a few UX improvements that would significantly enhance the user experience

1. Auto-Scroll Only Works on First Message
   For all subsequent messages, the chat window does not scroll automatically user must manually scroll down to view new responses.
   Suggestion:
   Fix the auto-scroll behavior so it applies to every new message, not just the first. This should trigger immediately after each model response is generated, ensuring users always see the latest message without interruption.
   Expected behavior:
   After every reply, the chat window automatically scrolls to the bottom, just like in ChatGPT and Gemini.

2. Fixed-Size Input Box (one line)
   The input text box has a fixed, small height and does not grow dynamically as the user types.
   Suggestion:
   Make the input box dynamically resize based on content length, it should expand smoothly to accommodate longer messages.

3. Sidebar Does Not Close on Click Outside
   The sidebar remains open when click outside of it in the chat area, feels unresponsive compared to ChatGPT or Gemini.
