feat: cases (reports, rating reviews, removal and deletion requests, appeals) and notifications

Cases are one queue for what someone has to decide, each with a thread (internal notes for those deciding), an
assignee and a decision. Reports about a product go to the teams of the catalogs hosting it and to moderators, and
only the reporter and moderators know who reported. A creator lowering a rating opens a rating review; a catalog's
owner asking to delete it opens a deletion request; a catalog's team can ask for a product's removal everywhere; the
person an action affected can appeal it once, decided by another moderator (an admin may decide their own, flagged).
Resolving carries the case out: the rating is lowered, the product removed, the catalog deleted.

Notifications reach people on the website (a bell with the unread count) and their proxies (realtime): moderators'
edits to their products, removals and restores, decisions and replies on their cases, membership decisions.

Also: moderators can restore a removed product, and a product's creator and moderators can see it when it's adult
without an adult account (getting and wearing it still need one).
