The "close tab on device" button in the Account menu is unnecessarily wide

[Aleksandra0056]

Describe the bug

After updating Firefox to 130.0.0, I noticed a new button called the "close tab on device" button, but it's unnecessarily wide.

Expected behavior

Fix the button width and change it from rectangle to square to be consistent with other buttons and with standard Proton widths.
