[#1364] [FIX] Disabled notifications on activities from blocked domains (unless actors are followed)
Post-merge fix / improvement to #1364 (closed)
Filters out notifications on activities by actors from blocked domains (unless they are followed).
Includes notifications for following but domain-blocked users in Notification.for_user_query/2
(previously notifications from domain-blocked users were not listed regardless of whether these users are followed).
