Add Confirmation Modal for Sign Out Action

[Zunairah-k]

Issue Description:

Currently, clicking the “Sign Out” button immediately logs the user out without any confirmation, which can lead to accidental sign-outs.

Proposed Solution:

Implement a confirmation modal that appears when the user clicks “Sign Out.”

The modal should ask:
“Are you sure you want to sign out?”

Provide two options in the modal:

• Confirm → Proceed with sign out

• Cancel → Close the modal and stay signed in

Benefits:

• Prevents accidental sign-outs

• Improves user experience by giving users control over their actions
