AI: Long Error messages from providers is not scrollable

[manaschubby]

Summary

When the error message from LLM provider is long and goes out of the viewport, the error message isn't scrollable and the end of the message is not visible/viewable.

Need to let it be scrollable so that the end of the message is also visible.

Description

Steps to trigger the problem (this is for Google's LLM Provider):

1. Say you have an API key who's quota is exhausted.
2. You make a request using the agent panel.
3. The agent retries the requests twice. Then shows the long error message.
4. You want to see the error message but you cant scroll on it.

Expected Behavior:

1. Error message should be scrollable.
   Actual Behavior:
2. We need to copy and paste the error into an empty buffer to see what the content at the end is.
