viewer: journal text for asset.acquisition_linked; a test that every event type the store writes has plain-language journal text

The acquisition link was added after the viewer's asset work and showed its raw event name in recent activity. The new test reads the event types from the store's replay arms, so the next new event without text fails it (checked: it fails without this fix).
