Previously, the calendar — along with the `/upcoming-events` page and the `.ics`… subscription feed — listed events from unlisted topics to everyone, because `EventFinder` scoped events with `Topic.listable_topics`, which only excludes private messages and never filters out unlisted (`visible: false`) topics. Unlisting a topic (manually, or as a side effect of spam flagging or a moderator action) therefore removed it from the topic list but left its event on the calendar for all users. This change makes `EventFinder`'s `listable_topics` apply the `visible` scope unless the user can see unlisted topics (`Guardian#can_see_unlisted_topics?`), mirroring how `TopicQuery` filters topic listings: staff and TL4 users still see events from unlisted topics, while everyone else no longer does.
