(#11036) task: remove redundant logout button from settings sidebar (#11050)

- Removed logout item from settings navigation drawer
- Removed logout locator and method from E2E tests
- Removed logout item from NavigationDrawer story

The logout functionality is now exclusively available through the menu
switcher, making the UI more consistent and reducing duplication.

Closes #11036
