Two readability passes over the work package activity tab, no behaviour change. The paginator's private methods are reordered to follow their call order so the file reads top-down from `#call`, and the three activity filter modes (`:all`, `:only_comments`, `:only_changes`) — until now bare symbols duplicated across the controller, paginator, journal components and the hidden form — move into a single `WorkPackages::ActivitiesTab::Filters` module so the modes have one source of truth and can't drift apart. The diff reaches beyond the paginator into the controller, several components and a form, since that's where the symbols were scattered.
