• A catalogue filter has a stable key and a kind: event (what happened), topic (what it is about) or mute (content to leave out). It has an id once the account has used it, null before.
• A written filter has key: null, kind: "written", its label (its first words) and its full text as definition, and two fields a catalogue filter does not have: terms, what it searches, in order, each term its own search; and keeps, the line saying which of the articles found it keeps, which the AI that judges them applies. A written filter saved before terms existed shows the searches it was saved with.

GET /filters lists the catalogue and the account's own filters.
