The dashboard and job pages show a 'Log out' control (POST /ui/logout) and a
'Signed in · <role>' label when a userservice session is active. Under basic
auth (no session) neither appears, so the fallback UI is unchanged.
Threads a template-only Session view (json:"-") from authctx into the
dashboard and job views. Tests assert the control renders only in session mode.
