feat(store): add a moderated publication as a fourth listing card master
The listing showed one popup, on a clean publication. This adds the opposite: an account you blocked, publishing something two labelers you listen to have both labeled, shown after clicking past the cover those labels put in front of the card. It is a fourth frontpage gallery card and a second store screenshot, so `storeShot` becomes `storeShots` and render-cws composes one 1280x800 tile per store capture (`brand/cws/screenshot-<capture>.png`, replacing `screenshot.png`). The publication is a fixture from top to bottom — no real publisher is going to model this — but nothing about how the popup renders it is: the labelers are real, and only their answers about the fixture are stubbed, so the pill names, their severity and the cover all come from the labelers' own definitions. The fixture publisher's card and the labels are seeded into the popup's own caches; a labeler that stops declaring one of these values fails the capture. The other captures are refreshed in passing: the popup gained a Share button since they were taken.
