R4 the client catches up: follow requests, followers, downvotes, dismissing, filtering a post, quote policies, statistics in detail

Follow requests answered on the persona's own profile and from the Notifications tab; its followers and the accounts it
follows listed there, a follower removed (asked first). Downvotes on threadiverse posts, after the public-vote notice.
A notification dismissed from its line. "Filter this post" from a card's menu, and the Filters page showing the posts a
filter holds. Who may quote the persona's own posts, and revoking a quote of one. Statistics: a server in detail with
"describe again", the ledger's events, the server's own days. The composer deletes an upload taken out before posting.
MediaType.Documents goes.
