Show suppressed badge on host cards during global maintenance windows

Global suppressions (target_type='all') have an empty target_name, so
the selectattr filter never matched them, leaving no visual indicator
when a global maintenance window was active. Pre-compute has_global_sup
before the host loop and OR it into the badge condition.
