Opening the Setup > Users page crashed with KeyError: 'locked' when the user database contained a user whose profile did not include the locked attribute. This could happen for users created via external connectors or older Checkmk versions.

The user list now treats a missing locked attribute as unlocked, matching the UserSpec type definition which already marks the attribute as optional.
