fix: update history method changes

[pradeepjha-microsoft]

Purpose

This pull request includes changes to the ClientAdvisor/App/frontend/src/api/api.ts and ResearchAssistant/Deployment/scripts/aihub_scripts/requirements.txt files. The changes focus on adding a new utility function to handle empty arrays and updating dependencies in the requirements file.

Improvements to API functionality:

• ClientAdvisor/App/frontend/src/api/api.ts: Added a new function isLastObjectNotEmpty to check if the last object in an array is not empty and used this function in the historyUpdate method to handle empty message arrays.
• ClientAdvisor/App/frontend/src/api/api.ts: Modified the historyUpdate method to return an error response when the message array is empty.

Does this introduce a breaking change?

• Yes
• [X ] No

Golden Path Validation - NA

const errRes: Response = {

• [nitpick] The error response should include a more descriptive statusText, such as 'Empty messages array' or 'Invalid message format'.

status: 500
