Update BI-copilot review mode logic for persistent context

[kanushka]

Purpose

Updates the BI-copilot chat review mode to ensure subsequent prompts maintain context from the temporary directory.

Changes

• Persist Context: Updated the next prompt flow so BI-copilot pulls from the temp directory if the user is still in review mode, rather than reverting to the base project.
• Review Mode Visibility: Ensured review mode is displayed by default following code generation.
• Cleanup Logic: Fixed an issue to ensure review mode is cleared when the user clears the chat history.
