[Issue] UX review for ConcurX TUI

[SophCarp]

ConcurX is a new extension to enable concurrent operations.

Details about the extension and instructions to install--> ConcurX README

The extension helps customer move faster and we'd like to pull into the overall functionality into the azd up experience. First we need to close the UX gap and alight to the azd practices and azd style guide.

Based on PR: #6368

Tasks:

• Diff UX from our current style guidelines
• Review extension interactions
• Give feedback/improvements
