Add sign out confirmation modal

[Zunairah-k]

Closes: #1224

PR Description

• Added a Sign Out Confirmation modal in the User Navigation Panel.
• The modal is functional and shows when the Sign Out button is clicked.

It's hard to review. Could you just commit only your changes and not anything un-necessary?

[Zunairah-k]

@Avdhesh-Varshney i only commited the changes that i made in the files to add that confirmation modal. could you tell me what's blocking the review further?

Hi @Zunairah-k, I've recently take a major change in repo by transforming the whole FE from JS to TS. So, you need to raise a new fresh PR in client folder.

Earlier one version is deleted and current TS version is not stable right now exactly. But we're working on it. Thanks 👍

[Zunairah-k]

@Avdhesh-Varshney since the new TS version isn’t fully stable yet, should I go ahead and re-implement my changes in client/ and open a fresh PR now, or would you prefer I wait until you guys finish stabilizing it?

[Avdhesh-Varshney]

Really appreciate your interest!
But it might be taking some time in stabilization of FE as the current codebase is larger and not easy to maintain solely.

So, Wait for some time for this feature implementation.

Thanks!

I would like to invite you in this process. This will definitely be a learning experience for you.
