fix: code quality issues

[Kanchan-Microsoft]

Purpose

This pull request includes minor improvements to error handling and code style in both the frontend server and backend test files. The changes focus on making exception handling more robust and clarifying test code by removing unnecessary assignments.

Error handling improvements:

• In src/App/frontend_server.py, added a comment to clarify that exceptions during websocket cleanup are intentionally ignored, as the websocket may already be closed.

Test code cleanup:

• In src/tests/backend/v4/config/test_settings.py, removed unnecessary variable assignments when awaiting tasks in test cases, improving code clarity and consistency. [1] [2]
