Reports, and who liked or boosted a post

Another's profile and posts can be reported from the client (/api/v1/reports): a category, words, and for a remote
account a copy to its server, which PrivaPub sends from its own actor, never naming the persona. Who liked or boosted
a post opens from its card's menu (favourited_by, reblogged_by). e2e: a report from a Mastodon account's profile
reaches PrivaPub's moderators forwarded, and a post's likes and boosts list the persona who gave them; the admin
helper the tests share moves to Support.
