fix: remove confirm() dialogs from both logout buttons

- Header logout (#logout-btn) already had no confirm (AuthManager.logout called directly)
- Settings panel (#logout-btn + #profile-logout) now call handleLogout() without confirm
- Both buttons redirect to login screen immediately — consistent behavior
