When the employees directory is enabled, look up the current user by their SSO
(= username) and show their full name + photo in the sidebar user menu.
- auth store: enrichFromDirectory() runs on login + fetchUser; sets
directoryname/directorypicture from employeesApi.lookup(sso). Best-effort -
falls back to the raw SSO when employees is off, the SSO is not in the
directory, or the lookup fails.
- displayName / avatarUrl getters; sidebar shows the photo (/static/employees/
<Picture>) + name over the SSO. Broken photos hide gracefully.
