Profiles: revert Service Status modal to admin-only

Active metadata source / media server / download source are app-wide
infrastructure, so the quick-switch modal is admin-only again:
openServiceSwitchModal() no-ops (with a toast) for non-admins, and the sidebar
Service Status loses its clickable affordance for them. Per-profile playlist
account selection will live on its own user-accessible surface, not here.
